Margeretta Is a Trained Opera Singer, Who Has Been Hired

Margeretta is a trained opera singer, who has been hired to give an exclusive gala concert by Moneybags, as a birthday present for his wife. Margeretta is superstitious and, having read the tea-leaves in her cup, decides not to do the concert. Moneybags is desperate to make her perform. Moneybags may:

A) Compel Margeretta to perform the contract, as this is the carrying out of a specific activity.
B) Not compel Margeretta, as this is a contract for personal services. He can bring an action for damages.
C) Compel Margeretta to perform the contract, as damages would be an inadequate remedy.
D) Not compel Margeretta, because contracts for personal services like this are unenforceable.
