Hi Rohan,

try with below code. 
global class updateContactOwner implements Database.Batchable<Contact>{

   global Database.QueryLocator start(Database.BatchableContext BC){
     String query = 'Select id, ownerId,Account.OwnerId from Contact'; 
     return Database.getQueryLocator(query);
   }

   global void execute(Database.BatchableContext BC, List<Contact> scope){
     List<Contact> conList = new List<Contact>();
     for(Contact con : scope){
       con.ownerID = con.Account.OwnerId;
       conList.add(con);
     }
     update conList;
    }

   global void finish(Database.BatchableContext BC){
   }
}

open annoumus window and run the below code. 
updateContactOwner  batch = new updateContactOwner ();

Database.executebatch(batch,200);


If this helps, Please mark it as best answer.
