Hey Anoop, 

I think that you should go for B.com Programme from Delhi College Of Arts and Commerce since when it comes to University Of Delhi, course like Bcom honours, Economics honours,English honours and Bcom programme are the most popular courses and very well recognised also.DCAC is more recognised than College of Vocational Studies and Bcom Programme is more beneficial and better than MMRB.

As the name suggests, College of Vocational studies is the go-to college for vocational courses, but these courses are job specific and a bit confined to their field so the jobs will be limited whereas if you go for Bcom programme you can pretty do everything that is included in MMRB and more. 

But, if you're sure you want to pursue something in Marketing management and retail business field, pick MMRB from College of Vocational Studies. 

Hope this helps!
