Answer:
What is entirely true about this contract is:
The contract is a VALID contract but is also a VOIDABLE contract on the part of Larry but NOT on the part of Sprint.
Step-by-step explanation:
As a minor, Larry (he was under the age of 18 when he signed the contract with Sprint) lacks the contractual capacity to enter into the contractual relationship with Sprint. But since he has signed the contract in exchange for the purchase of the cell phone, Larry can either honor the deal or void the contract. This is why the contract is said to be valid but voidable at Larry's behest. However, after Larry has turned 18, if he has not done anything to void the contract, then the contract with Sprint can no longer be voided.
