Explanation:

- When A buys goods from B by misrepresentation, A gets voidable title, not void.

- If A pledges these goods to C (who acts in good faith and without notice of misrepresentation), the pledge is considered valid under Section 178A of the Indian Contract Act.

- This protects innocent third parties (like C) who trust A's apparent ownership.

- Options explained:

- Option 1: valid (Correct Answer) – The pledge is valid if C acts in good faith.

- Option 2: void – Not correct, as the contract is not invalid from the beginning.

- Option 3: voidable – Not correct for the pledge; it's the sale that's voidable.

- Option 4: invalid – Similar to "void," not correct here.
