Hi Navneeth,

You need to write below line only when you want to create the object or instance of Student object.
Student__c std = new Student__c();
or if you want to create new Record base on old record etc. And Trigger will fire only when DML will happened. 

But in our case we dnt need to create any object. Only below trigger we need to use.
 
trigger StudentTrigger on Student__C( before Insert)
{
	for(Student__c sc : Trigger.New)
	{
		sc.Country__C = 'INDIA';
	}
}


Please mark this as solution if this will help you. So that is some one has same issue this post can help other

Thanks
