Answer:
B. He is not responsible for damages because reasonable care was given.
Step-by-step explanation:
As shown in the details, he was specifically given a key to unlock and lock the shed for the delivery of wood. The details also state that the burglars broke into a locked shed. This means that he locked the shed behind him, and therefore is not at fault.
Further proof is that the burglars also caused damage when breaking in, which meant they did not have access to the key in order to open it. This also demonstrates that David was responsible in the care with the key.
Hope this helps!!
