Final answer:
The correct answer is A: if Larry affirms the contract after reaching the age of majority, Computer Heaven can sue him for breach of contract. Contracts with minors are voidable at the minor's discretion, and become binding if they affirm the contract post-majority.
Step-by-step explanation:
Concerning the scenario where Larry failed to make payments for the computer equipment after reaching the age of majority, the correct answer is A: Although the contract is unenforceable against Larry, if he affirms the contract after he reaches the age of majority, the seller will be able to sue him for breach of contract. This is because contracts made by minors are typically considered voidable at the discretion of the minor, but they can become binding if the minor, upon reaching the age of majority, takes actions that affirm the contract. Larry's initial down payment and use of the computer to complete high school may indicate an initial affirmation, but unless he reaffirms after reaching majority, he cannot typically be held accountable for the remaining payments.
Option B is incorrect as Computer Heaven can't automatically sue Larry for breach upon him turning adult, they would need evidence of affirmation after he reached the age of majority. Option C is incorrect since parents are generally not liable for the contracts entered into by their minor children, and option D is incorrect because a transaction with a minor is voidable, not void, and thus the title may have passed unless the contract is disaffirmed by the minor.
