It’s a good idea to draw the local rule in full. It makes it easier to think about.
Ask yourself which rules are the most restrictive? We already have M. We already have H in common between P and T.
The only other rules are F can’t go with K and K can’t go with J.
Both rules are about K and the question wants us to put K in.
K needs J, so we can’t put K in the first row.
We can’t replace J with K in the second row. Then there would still be no J with K.
We can’t replace H with K. Then there would be no variable in common between the two groups.
So we have to put K in the place of G. That doesn’t break any rules. We still have H in common and K has its J. B is CORRECT. Here’s what it looks like:
