a landlord leased an apartment to a makeup artist pursuant to a two-year residential lease. one year after the commencement of the lease, the makeup artist subleased the apartment to a waitress pursuant to a sublease agreement. the landlord approved the sublease, the makeup artist vacated the apartment, and the waitress moved in. there was no provision in the sublease agreement regarding who would have ultimate responsibility for the payment of rent to the landlord. for the first five months of the subtenancy, the waitress made rent payments directly to the landlord. later, she stopped these payments altogether. whom should the landlord sue for the unpaid rent? (a) the makeup artist, because she transferred less than all of her interest in the lease to the waitress. (b) the waitress, because her actions during the first five months of the subtenancy established her intent to assume the makeup artist's duty to pay rent. (c) the waitress, because she is the assignee of the lease. (d) neither party, because the lease terminated when the makeup artist vacated the apartment.
