It's very simple. as the question mentions, the committee is to be formed comprising 7 members such that there is a simple majority of men and at least 1 woman.

Now keeping men in the majority and at least 1 woman in the committee, we are left with 3 choices only.

A. 1 woman and 6 men (1W+6M)

B. 2 women and 5 men (2W+5M)

C. 3 women and 4 men (3W+4M)

Any other combination does not fall in line with the conditions mentioned in the question.
