Can someone please assist. I am trying to query for ALL Opportunities and trying to make all the Opp owners sync up with the Account owner:

global class DealerDealOwnerSync implements Database.Batchable<sObject>{
   
    String jbrooks = [SELECT Alias, Id FROM User where alias = 'jbrook7'].id;
    String api = [SELECT Alias, Id FROM User where alias = 'SFAPI'].id;
    String wendy = [SELECT Alias, Id FROM User where alias = 'wkrame1'].id;
    String dwetl = [SELECT Alias, Id FROM User where alias = 'DWETL'].id;
    String ActRecTypeID = [SELECT Name, Id, DeveloperName, SobjectType FROM RecordType where SobjectType = 'Account' and Name = 'Activated'].Id;
    Integer iSize = 0;
   
   
    //TESTING FROM A BUTTON   
    public DealerDealOwnerSync(ApexPages.StandardController stdController)
    {        
      //clsContactOwnerSync();     

    }
   
    public DealerDealOwnerSync()
    {        

 
    }
   
    global Database.QueryLocator start(Database.BatchableContext BC)
    {
      return Database.getQueryLocator('Select Id, OwnerId, Name, CloseDate,Account.OwnerId, Account.Id,Account.Owner.IsActive,Account.Active__c, Account.Name, Account.GMF_ACF__c from Opportunity where stagename != \'DECLINE,WITHDRW\' and Account.recordtypeid = \'01230000000DD54AAG\' and account.owner.House_Account__c = false and account.owner.isActive = true and Account.LastModifiedDate = Last_Month and Account.LastModifiedById = :wendy and Account.Active__c = \'Y\''); // Select Id, OwnerId, Name, CloseDate,Account.OwnerId, Account.Id,Account.Owner.IsActive,Account.Active__c, Account.Name, Account.GMF_ACF__c from Opportunity where stagename != \'DECLINE,WITHDRW\' and Account.recordtypeid = \'01230000000DD54AAG\' and account.owner.House_Account__c = false and account.owner.isActive = true and Account.LastModifiedDate = Last_Month and Account.LastModifiedById = :wendy and Account.Active__c = \'Y\'
    }
   
    global void execute(Database.BatchableContext BC, List<sObject> scope){
        List<Opportunity> dealsToUpdate = new List<Opportunity>();
        for(sObject obj : [Select Id, OwnerId, Name, CloseDate,Account.OwnerId, Account.Id,Account.Owner.IsActive,Account.Active__c, Account.Name, Account.GMF_ACF__c from Opportunity where stagename != 'DECLINE,WITHDRW' and Account.recordtypeid = :ActRecTypeID and account.owner.House_Account__c = false and account.owner.isActive = true and Account.LastModifiedDate = Last_Month and Account.LastModifiedById = :wendy and Account.Active__c = 'Y']){

            Account a;*/
            Opportunity[] oppOne = a.getSObjects('Opportunities');
            if(oppOne != null){
                for(Opportunity o: a.opportunities){
                    if(o.OwnerID != a.OwnerID){ 
                        Opportunity mOpportunity = new Opportunity();
                        mOpportunity.Id = o.Id;
                        mOpportunity.OwnerID = a.OwnerID;
                        dealsToUpdate.add(mOpportunity);
                       
                        iSize = iSize + 1;
                        system.debug('**************ISIZE:' +iSize);
                       
                        if(iSize == 1000)
                        {
                            update dealsToUpdate;
                            System.debug('********UPDATE COUNT: ' + iSize);
                            dealsToUpdate = new List<Opportunity>();

                        }             
                    }
                }
             }
          }

                 dealsToUpdate = new List<Opportunity>();

    }

    global void finish(Database.BatchableContext BC)
    {
        //ID d = Database.executeBatch(new DealerDealOwnerSync(),100);
    }
