To better understand classwork homework, let them know of any reasons you’d be struggling, turning in work late for potentially partial credit instead of a zero are all things I found to be useful through school at various levels.
The verb, I assume, is "flew" and the tense is A. past.
if it was any of the other options, "fly: would be in a dfferent form :
B. present
he flies
C. present
<span>
participle
he did something, flying
D. past participle
he has flown
</span>
