if i am not wrong i dont think so history is the subject of commerce students. They have Cost Accounts, Management Accounts, Income & Sales tax, Operation research, Economics in 3rd year. As well as in 1 st & 2 nd year students don't have history at all. Then why samrat is a history teacher or if he is then he has to attend B.A class not B.Com at all.
B'coz commerce has no link with history.
