Answer:
A
Explanation:
It can happen at any time.
Progress means "forward or onward movement toward a destination". -Google
That means that the verbs can happen any time. "The door creaked," would be simple past.
Simple present would be, "<u>Opens</u> the door and it <u>creaked</u>".
This shows that it happened now, but only once.
For past progressive, I have no idea. Maybe it's, "Opened the door and it creaks."
