If it appears from the nature of the case that it was the intention of the parties to any contract that any promise contained in it should be performed by the promisor himself:

the promisor may employ any other person who is party to the contract to perform the promise
any relative of the promisor may perform the promise on behalf of the promisor
must be performed by the promisor himself
any person who is not a party to a contract may perform the promise

The correct answer

is C. must be performed by the promisor himself.

A promise is a legally binding agreement between two or more parties. The promisor is the party who makes the promise, and the promisee is the party to whom the promise is made. In order for a promise to be enforceable, it must be made with the intention of creating a legal obligation.

If it appears from the nature of the case that it was the intention of the parties to any contract that any promise contained in it should be performed by the promisor himself, then the promisor must perform the promise himself. This is because the promisee has relied on the promisor’s promise, and the promisor would be in breach of contract if he did not perform the promise.

Options A and B are incorrect because they do not take into account the intention of the parties. Option A states that the promisor may employ any other person who is party to the contract to perform the promise. However, if the parties intended that the promise be performed by the promisor himself, then the promisor cannot delegate the performance of the promise to another party. Option B states that any relative of the promisor may perform the promise on behalf of the promisor. However, this is also not correct, as the parties’ intention is the most important factor in determining who must perform the promise.

Option D is incorrect because it states that any person who is not a party to a contract may perform the promise. However, this is not always the case. If the parties intended that the promise be performed by the promisor himself, then only the promisor can perform the promise.
