Dear Student,
It's nice to hear from you that you have a special interest in accounts and business. Both BBA and B.com have an accounts and business in it's curriculum and on the basis of market data the scope of BBA is better than ordinary B.com. But I shall suggest you to go for B.com hons. as it has a curriculum which teaches you many other important subjects apart from accounts and business and also has great demand in market. So if possible i suggest you to go for B.com hons. and if not then out of BBA or B.com you shall go for B.com. Hope this might help you.

Hey.

I would suggest you to opt for B.com if you are inclined towards accounting subject. BBA is more of management and business studies including more of commercial aspects. Also maths would help you in your future undertakings.
Hope this helps. All the best.
