We know that Phoebe has agreed to tutor Indira's daughter in math. Phoebe borrowed her friend Colin's car to drive to Indira's house, and she paid $2 to park the car in an underground lot close to Indira's apartment building. The lot is owned by Navin. Navin does not take possession of the car or the car keys at any point, so that use of his parking lot constitutes a licence, not a bailment.

When opening the car door, underneath the car she discovered an envelope with $500 in it. The envelope was addressed to Sally Bowles, a real estate agent who worked at an office in the building where the lot was located.

With regard to the $500 in the envelope that Phoebe discovered underneath the car, which of the following is correct?

a) Colin's claim is superior to either Phoebe or Navin, because the money was found under his car.

b) Finders, keepers. Phoebe's claim is superior to everyone.

c) Navin's claim is superior to Phoebe or Colin because the money was found in his lot and he controls access to the lot.

d) Finders, keepers. Phoebe's claim is superior to either Navin's or Colin's claim.
