Answer: TRUE.
Explanation: A contract can be defined as an agreement which the law will enforce in some way. A legally binding contract must contain at least a commitment or offer, by an offeror to and accepted by an offeree to do something in the future.
A breach of contract in legal terms can be said to be an unjustifiable failure to perform under the terms of a contract when performance is due. This can be said to be a civil wrong which in any case can be sued for.
In the question, Kathy and Tom( the offeror) have entered into a contract with Mike (the offeree), assuming there's a breach of contract, which is a civil wrong, then Mike has every right to sue. Correct answer is TRUE.
