a. i want to try out for the team.
b. parveen is anxious to a fault.

Explanation:

Infinitive phrases use "to" with a verb. Verbs are action words.

"to try" is a verb in the infinitive form.

B. "to a fault". A fault is a noun, a thing.

C. "to Toronto". Toronto is a noun, a place.

D. "to college". College is a noun, a place.

If you study French, verbs you learn are always "to" something in the "infinitif" before conjugating. That may help you remember.
