Explanation:

Let’s break it down:

- Impossible agreements are those that can’t be performed at all—the act is physically or legally impossible.

- Option 1: Illegal

? This isn’t quite right. An agreement is illegal if it’s forbidden by law, but not all impossible agreements are “illegal” in that sense.

- Option 2: Void

? Now we’re onto something. Void means it has no legal effect—like it never existed. Impossible agreements are void because the law basically ignores them.

- Option 3: Valid

? Nope. If a contract is impossible, the law says it doesn’t count as valid.

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

? Since neither illegal nor valid fits, this isn’t the answer.

Correct Answer: Option 2 (Void)
