Hi there,

Chartered accountancy course is not offered by any college. It is offered by ICAI (Institute of chartered accountancy of India). Students have to register themselves on ICAI portal.

While you can pursue b.com form another college.
Some of best b.com college are following:

Hindu College
Zakir hussain delhi College
Hansraj College
Aditi Mahavidyalya
SRCC delhi
KMC delhi
Delhi College of commerce and arts

Hope it helps you
Good luck!
