Explanation:

Let’s break this down:

- Option 1: Contract

Not quite. For a contract, you need acceptance, consideration, and intention to create legal relations. The proposal becoming accepted is just one step.

- Option 2: A promise

Getting warmer, but it’s not the full picture. Acceptance of a proposal does create a promise, but it doesn’t stop there.

- Option 3: An agreement

Yes—when a proposal is accepted, you have an agreement. It’s an agreed set of terms between two or more parties.

- Option 4: Both (b) and (c)

This is the real answer. Once a proposal is accepted, you have both a promise and an agreement. Legally, both are created at the point of acceptance.

Correct Answer:

- Option 4: Both (b) and (c)
