The correct answer is (a) Two years.
Under the Transfer of Property Act, 1882, a tenant who holds over after the expiration of the tenancy period is said to be a tenant at sufferance. The landlord may either evict the tenant or accept the tenant’s holding over and create a new tenancy. If the landlord accepts the tenant’s holding over, the new tenancy will be for a period of two years.
Option (b) is incorrect because the period of effect of holding over is not one year.
Option (c) is incorrect because the period of effect of holding over does not depend on the parties.
Option (d) is incorrect because the period of effect of holding over is not three years.
