Question

Our President is a man_______people respect
Who
Whom
Whose

Answer 1

here's a little trick:

if we answer this question with "him" then the filler of the blank in this question will be "whom" but if it is answered with "he" then the filler will be "who".

who does the people respect?
--the people respect him (president)

so the answer is "whom".
