Answer:
A. it is treated by the lessee as no residual value.
Explanation:
If the expected residual value is in assurance or unguaranteed, that's the economic and accounting product of the lesses
Furthermore, the guaranteed residual value also affects the computation of the minimum lease payment and the capitalised amount for an asset i.e. leased, lease obligation for the lessee
The promised residual value is an extra lease payment that can be paid in real estate or in cash, or both
Although the unguaranteed residual value, on the other hand, stays the same because no residual value will be impacted with respect to the estimation of the total lease payment and the capitalised amount for an asset, i.e. rented, lease contract.
