B) Bailment for mutual benefit
In a bailment for mutual benefit, both the bailor (the person delivering the property) and the bailee (the person receiving the property) stand to gain something. In such a situation, the bailee is required to exercise a greater degree of care because they benefit from the arrangement, and therefore they have a higher duty to protect and preserve the bailed property. This typically involves a duty of ordinary care, which means taking reasonable precautions to prevent damage or loss to the property.
