Answer:
E) In the majority of states, the landlord is required to remove the previous tenant or break the agreement with the new tenant.
Explanation:
The landlord will be required to have the previous tenant Eliza who is illegally( we are assuming) occupying the apartment, leave the apartment or he would be breaking the agreement with the new tenant. In some states in the US such as Chicago, the landlord would have to serve a notice to the tenant, and begin formal proceedings after which he may proceed to file a forcible entry or detainer action against the tenant if he remains in the property after expiration of appropriate number of days since notice was served. Eviction proceedings are relatively fast(a few weeks, unless the tenant files a defense) and are handled by local courts He may have to reimburse and settle the new tenant for any damages suffered.
