B.Com

Doing both at the same time is manageable to some extent but prioritizing both of them is quite difficult. I would suggest that if you are planning to do any professional course like CA CS CMA or any other, it would be best if you pursue your graduation from distance learning. If you take regular college it would get really difficult for you to manage both of them (saying that because of my personal experience)
Also, there are times when some exam dates of CA & B.Com from DU clash with each other, like one of my friends is doing CA with B.Com (regular college) and one of her exams on 25th May got clashed, so she missed B.Com exam (I don't know how and when will she be able to give that again) but she gave preference to CA that means she's clear with her priorities, so it's very much important before doing any course to know your priorities and work accordingly. Coming to the syllabus, honestly, you won't find much difficulty in doing and completing the B.Com syllabus while pursuing CA since most of it gets covered in CA. To conclude I would say go for it, cover both the courses, know your priorities and choose wisely from where will you do B.Com. All the best!
