Answer: d. no no
Step-by-step explanation:
When using operating leases, the rent is paid on a straight line basis meaning that rent will not increase and uses an even figure over the entire term of the lease.
The even figure already accounts for the increase in rent and incorporates it so there is no need to increase the rent figure in the 6th year.
Interest payment is not part of an Operating lease as this kind of lease involves on rental payments.
