B

1) If I am meeting the principal and the vice-principal, I am visiting the school.
Can be false: I meet the principal and the vice-principal whenever I visit the cafe. - does not contradict to the initial statement.
Therefore, If I meet the principal and the vice-principal, I may visit the school or the cafe (not the school)

2) If I am meeting the principal but not the vice-principal, I am not visiting the school.
Denial test: I am meeting the principal but not the vice-principal ---> I am visiting the school. --> I meet the principal and the vice-principal whenever I visit the school.
there is contradiction. Therefore, the statement must be true.

3) If I am not visitng the school, I am not meeting the principal and the vice principal.
The same reasoning as for 1).

Question # 20: I meet the principal and the vice-principal whenever I visit the school.

If this statement is true, which of the following must also be true?

1) If I am meeting the principal and the vice-principal, I am visiting the school.
2) If I am meeting the principal but not the vice-principal, I am not visiting the school.
3) If I am not visitng the school, I am not meeting the principal and the vice principal.

(A) I only
(B) II only
(C) III only
(D) I and II only
(E) II and III only

1) If I am meeting the principal and the vice-principal, I am visiting the school.
I could be meeting them out of the school. so not true.

2) If I am meeting the principal but not the vice-principal, I am not visiting the school.
If I visit the school, I meet both. If I am not meeting both, then I am not visiting the school. I am meeting the principal somewhere else out of the school. True.

3) If I am not visitng the school, I am not meeting the principal and the vice principal.
I could be meeting both somewhere else other than school. so not true.

Only B.

Thank you guys for great explanations.
Here are OE and OA. I didn't like below explanation, although it leads to urs.

Explanation (Crack GMAT)
This is best attempted through the process of elimination.
All that the given statement contends is that if I am visiting the school, I am meeting the principal AND the vice-principal.
In light of this, statements I and III are not valid.

Hence (B) is the correct answer.
