Answer:
A. Mike and Tom are bound to honor the contract because they are in a fully disclosed agency relationship.
Explanation:
In the scenario, the facts are:
1. Mike expects Tom to have completed the work by the time he gets back in three weeks.
2. Tom’s team needs asphalt roof shingles to install a new roof but Tom does not have a regular supplier.
3. Tom has the authority in Mike’s absence, Tom signs a sales contract on behalf of Mike to obtain the shingles from a third party.
4,Tom informs him about this contract.
5. Mike neither ratifies nor repudiates the contract.
With these facts in place, it is obvious that they are in a fully disclosed agency relationship, and the contract will be honored.
