1. (A) am
2. (A) have
3. (C) had tried
in number 2, if im not wrong, there's a redundancy or a grammatical error in the sentence
they should have left the word "got" off, or the word "have"
it should be like this:
If you got that job....
If you have that job....
ps: im not exactly sure in question 2 either the answer is had or have
