Answer:
A) The geographic restraint is reasonable.
Step-by-step explanation:
Generally non-compete agreements are done between employees and their employer and in order for them to be enforceable they must be reasonable and the employee must be compensated in some way (usually when the contract is signed a special compensation must be set, like a high salary or bonus, etc.).
In this case, the non-compete agreement is made between the seller and buyer of a business. The agreement includes a specific geographic restriction and lasts 4 years, so the agreement would be considered valid by a court. Generally if the non-compete agreement was between an employee and his/her employer and lasted that long it wouldn't be enforceable, but for a business a 4 year period is reasonable.
