What does Section 40 of contract law deal with?

Section 40 of contract law addresses who must perform a contract, specifically outlining the obligation of the parties involved in a contractual agreement. This section is crucial because it establishes the expectations for performance and clarifies the responsibilities each party has in fulfilling their contractual duties.

When a contract is formed, it is important to clarify not just the terms but also who is responsible for delivering on those terms. This ensures that each party knows their obligations and can be held accountable if they fail to perform as agreed.

While the other options touch on relevant aspects of contract law, they do not accurately capture the focus of Section 40. Joint promises, rights of promisees, and liabilities of joint promisors are discussed under different sections or provisions within contract law, making option A the most appropriate choice for what Section 40 specifically addresses.
