Answer: d. any of the choices.
Explanation:
Chaz is not to transfer the duties to a third party if Dolly got into the agreement with Chaz for any of the following;
- If Dolly places special trust in the ability of Chaz to perform the maintenance then that trust should not be broken by transferring the duties to a third party. Dolly went into that contract because they trusted in the abilities of Chaz.
- If Dolly went into the contract due to the personal skills or talents of Chaz, the duties against would be non-transferable. Chaz's skills were the reason the contract was signed, if these skills are not to be used then the contract will be baseless.
- By signing with Chaz, Dolly expects a certain level of performance. If the performance that will be made by a third contracting party is materially different from the one that Dolly would have expected from Chez, the duties will not be transferable.
