Answer:
The correct answer is: possessive
Explanation:
Whose is the possessive form of the pronoun "who", which means that it is used to mention the thing a person owns (possession). If we break down the sentence, the function of this word will be more clear:
A car is parked in front of a driveway.
This car belongs to someone.
We are trying to find out who has this car as their possession.
"whose" links all this information into a single sentence: We're trying to find out whose car is parked in front of our driveway.
