Hi Mansoor S 5

First you need to insert account record and then use that account id in the opportunity. Please follow the below steps

Account acc = new Account();
acc.Name = 'Burlington Textiles Corp of America';
acc.mail = yahoo@yahoo.com;
insert acc;

then now you can reference account id in the below opportunity record.

Opportunity oppty = new Opportunity();
oppty.account = acc.id;
insert oppty;

Please mark it as a best answer.

Hi Mansoor,
You have to give the field name as accountid while populating lookup value in apex class.You should give lookup recordId not name 
Public opportunity op = new opportunity();
op.accountid = '0012v00002xxxxxxx';


Hope this helps you
