Answer:
c. protect lessees against lessors who abuse leased assets.
Explanation:
The residual value guarantee may be defined as a guarantee that is made to the lessor where the value of an underlying asset will become at least some specified amount at the end of the lease. The guarantee is given by the party unrelated to a lessor.
The residual value guarantee provides to protect the lessor against the lessees who tries to abuse the leased assets. It does not protect the lessees against the lessors.
