Yes answer is D here.

Here is my calculations for each choice:

No. of students dislike Brussel sprouts who dislike Lima beans = 3/5 * 2/3N = 6/15N

1) Total # of students N = 120

No. of students dislike Brussel sprouts who dislike Lima beans = 2/5N = 2/5*120 = 48- Suff.

2) 40 of the students like lima beans

This is nothing but 1-2/3 N = 1/3N

So 1/3N = 40 --> N = 120

No. of students dislike Brussel sprouts who dislike Lima beans = 6/15N = 6/15*120 = 48 - Suff.

So answer is D.

Right ?
