B.Com LLB is available in Guwahati, through, Guwahati University, NEF Law College. However, there are several other colleges providing integrated Law degree but you need to check with them individually whether they give B.Com LLB or not.

Dear Afzal,
If your wife having aim for teacher than she can pursue B.ed for school teacher otherwise she can go for Net exam than apply for College level professorship and even she start teaching profession after Phd programme too.
So decide the way according to her interest and passion.
All the best
