Dear Aspirant,
The combination you have proposed is the best option if you are aiming for CA in your future. You might not be needing much of calculus in your future but mathematics in your +2 will help your analytical thinking which is very important in a professional course like CA.
Moreover, in your first test in CA, CPT( Common Proficiency Test ), entry level test for CA, you will be needing some mathematics there too.
Go for Commerce + Mathematics.
All the best. Thanks.
