A Broker Is Hired to Collect Rents in an Apartment

A broker is hired to collect rents in an apartment house. The rents are due January 1, and the broker is able to collect all but one of the tenants' rents. The next day the owner dies, and the day after that the delinquent tenant refuses to pay the broker, saying that the owner's death voided the property management contract. The tenant:

A) cannot refuse to pay because the rent was due January 1 and the owner did not die until January 2
B) cannot refuse to pay because the tenant had previously recognized the agent and paid rent for prior months
C) cannot refuse to pay because the agent's authority continues until an administrator or executor is appointed
D) under these circumstances, the tenant was right not to pay
