A 2-year lease on a property has expired.

Comprehensive and Detailed Explanation (150–250 words):

When a lease expires and the tenant remains in possession with the landlord’s consent, the tenancy becomes a tenancy at will. This means the tenant occupies the property with the owner’s permission but without a fixed lease term. Either party may terminate the tenancy with proper notice, as required by law.

A: Tenancy from year to year (periodic tenancy) arises when rent is paid at regular intervals without a defined end.

C: Tenancy in common refers to ownership, not leasing.

D: Tenancy at sufferance occurs when the tenant remains without the landlord’s consent.

Since the landlord has permitted occupancy during negotiation, the correct answer is B: tenancy at will.
