Hey Sourabh

For taking admission in Commerce stream you need to calculate your best four subjects by taking english along with maths, business studies and commerce (for no marks to be deducted , you can also check out lest C1 for DU https://university.careers360.com/articles/delhi-university-admissions-how-calculate-best-of-four-marks ) or you can take any one of IP,Business mathematics,Legal studies etc (list c2) with a deduction of 1% for each subject taken.

If you take physical education your marks will be deducted as per 2.5% deduction rule. So, you should not add physical education (according to me) if you are not ready to lose 2.5% out of your total percentage.
