B

Explanation:

A minor (under the age of legal capacity) has limited contractual capacity, and contracts entered into by minors are generally voidable or unenforceable against them. Even if a minor misrepresents their age to borrow money, they cannot be sued for fraud, as this would indirectly enforce the contract against them, undermining the protection afforded to minors. The lender may have other remedies, but suing for fraud is not permissible. Option A is incorrect, as minors are protected from such lawsuits. Option C is incorrect, as the minor is not typically liable to return the money under contract law. Option D is incorrect, as option B is accurate. The answer “B” is as provided in the attachment.
