There is a problem with the question, the word void should not be there. A void agreement is simply not enforceable since it is not valid. So I will assume that they both reached a valid agreement and it was a typing mistake.
Answer:
a. True
Step-by-step explanation:
If two (or more) parties engage in a valid contract that includes certain specific conditions that are necessary in order to complete performance, and these conditions are met by one of the parties, then the other party must perform their part. In other words, if James performed all the conditions that were included in their contract, then Kamanda should hand over the toaster to James.
