Explanation

"It is okay for Balls to subcontract" is the correct answer. This question is testing whether you know that subcontracting can be a remedy in a contract.

This is a difficult question because you don't get a lot of context- it's based on a similar question in the exam- but just remember subcontracting can be a solution if one party can't fulfil their obligations in a contract. This is better than them breaching the contract. See p.89 for more information on subcontracting
