A is going on vacation in the middle of December when the temperature will be below zero degrees Celsius. His policy requires that while he is away, A must arrange to have his house looked after by someone. A makes arrangements with his friend B, who agrees to regularly look after the house while A is away, and A gives B a key. While A is away, the furnace, which was installed three weeks ago by the manufacturer, stops working and the house temperature drops below zero. As a result, the pipes in the upstairs washroom freeze and then burst, causing water damage throughout the entire house. An investigation discloses that B, believing that the house would be fine, decided not to check the house as he had promised to do. In this situation,
a. A's insurance company will not have to honour the policy and restore the house.
b. A's insurance company will only honour the policy and sue the furnace manufacturer to recover the cost of restoring the house.
c. A's insurance company will only honour the policy and restore the house.
d. A's insurance company will only honour the policy and will sue B to recover the cost of restoring the house.
e. A's insurance company will honour the policy and sue both B and the furnace manufacturer to recover the cost of restoring the house.
