Final answer:
The tenant can leave the premises with no further lease obligations based on the lease agreement provision that states the landlord will supply water.
Step-by-step explanation:
The tenant can leave the premises with no further lease obligations based on the provision of the lease agreement that states the landlord will supply water. If the water to the building was cut off because the landlord had not paid the water bill, it is considered a breach of the lease agreement by the landlord. This breach of contract relieves the tenant from their lease obligations, such as paying rent or fulfilling any other terms of the lease.
