The correct option is B Valerie recently lost her job and, for the last three months, has neglected to pay her landlord the monthly rent they agreed upon in writing when she moved into her apartment eight months ago.
Valeria's apartment lease document required her to pay the rent on time. By failing to pay the last three month's rent, she has forfeited the agreement. Hence, Option B is correct. The rest of the options mention violations of any rule by the landlord, not the tenant, hence incorrect.
