The correct answer is C. Both A and B.
A sub-bailee is a person to whom the actual possession of goods is transferred by someone who has a present right to possession of them as bailee of the owner. This means that the sub-bailee must have a legal right to possess the goods, which can be derived from the original bailment agreement or from another source, such as a lease or a contract of sale.
For example, if you borrow a car from your friend, you are the bailee of the car. If you then lend the car to your neighbor, your neighbor is the sub-bailee of the car. In this case, you are the original bailor, your friend is the original bailee, and your neighbor is the sub-bailee.
The sub-bailee is responsible for the care of the goods and must return them to the original bailor in the same condition they were in when they were received, unless the goods have been damaged or destroyed through no fault of the sub-bailee.
If the sub-bailee fails to return the goods or fails to take care of them properly, the original bailor may be able to sue the sub-bailee for damages.
