I agree with James Loghry. Please check you have any class with "SelectOption" then please delete the class and try again

Please try below code. 
public class ChildRelationshipExample {
    
    public List<SelectOption> options;
    
    public List<SelectOption> getOptions(){
        return options;
    }
    
    public ChildRelationshipExample(){
        
        options = new List<SelectOption>();
        Schema.DescribeSobjectResult r = Account.SobjectType.getDescribe();
        List<Schema.childRelationship> c = r.getChildRelationShips();
        
        for(schema.childRelationship x:c)
		{
			if(x.getChildSObject() != null)
			{
				String name = ' '+x.getChildSObject();
				SelectOption op = new SelectOption(name,name);
				options.add(op);
			}	
        }
        
    }
    
    
}

Please let us know if this will help you

Your constructor looks okay to me.  If the previous options don't work, check to make sure you don't have an Apex class (Setup->Develop->Apex Classes) named "SelectOption" that could be interfering with your save.

Hi,

Amit absolutely you are right...!

Vijendhar, You have a class named as "Selectoption" in your organization. Please delete or rename the class, then try again to save your code.

Thanks.
