The correct option to fill in the blank is beside.

The other options are not as appropriate:

• Besides means "in addition to" or "other than". It would not be accurate to use "besides" in this context, as Rahul did not park your car in addition to a scooter.
• Close means "near" or "not far away". It would not be accurate to use "close" in this context, as Rahul did not park your car very close to the scooter.
• With means "in the company of" or "together with". It would not be accurate to use "with" in this context, as Rahul did not park your car together with the scooter.
