Answer:
The correct answer is letter "B": a valid delegation because the duty is mechanical and nonpersonal in nature.
Step-by-step explanation:
In contract law, delegation is the act of assigning the duties -not the rights- established in a contract to a third party. The third party in charge of performing the duties is called the delegate who was assigned by the obligor. For delegations to be valid they must meet the completeness test and the sufficient standard test.
Duties cannot be delegated when the performance depends on the personal skills or talent of the obligor or when special trust has been placed on the obligor (personal in nature duties) or when the contract forbids delegation.
Then, Collin's delegation to Levi for painting Jocelyn's house is valid since the duty does not require any special talent from Collin, thus, the performance is not personal in nature.
