How to find same values in two different data sets of different sizes?

I have two data sets of unequal length. A = [1 2 3 4 5; 6 7 8 9 0; 5 4 3 2 1; 0 9 8 7 6] and B = [3 4; 8 9; 3 2; 8 7]

Columns 3 and 4 of data set A are the same as all of data set B.

How do i obtain the column indices representing which part of A is the same as B answer desired is [3; 4]

Thanks for all the help in advance!
