The correct answer is: B. The promisor is not responsible for non-performance, nor does he thereby lose his rights under the contract.
A promise is a declaration of an intention to do or not to do a particular thing. A contract is an agreement between two or more parties to do or not to do a particular thing. A promisor is the person who makes a promise. A promisee is the person to whom a promise is made.
In the case where a promisor has made an offer of performance to the promise and the offer has not been accepted, the promisor is not responsible for non-performance, nor does he thereby lose his rights under the contract. This is because the offer has not been accepted, and therefore there is no contract.
The promisor may still be able to enforce the performance of the promise if the promisee has accepted the offer by performing some act or by making a promise in return. However, the promisor cannot enforce the performance of the promise if the promisee has not accepted the offer.
Here are some brief explanations of each option:
- Option A: The promisor is responsible for non-performance, but he does not lose his rights under the contract. This is incorrect because the promisor is not responsible for non-performance if the offer has not been accepted.
- Option B: The promisor is not responsible for non-performance, nor does he thereby lose his rights under the contract. This is the correct answer.
- Option C: The promisor is not responsible for non-performance, but he loses his rights under the contract. This is incorrect because the promisor does not lose his rights under the contract if the offer has not been accepted.
- Option D: The promisor can enforce the performance of the promise. This is incorrect because the promisor cannot enforce the performance of the promise if the offer has not been accepted.
