Answer:
D) nonnegotiable, because it calls for payment in shirts.
Step-by-step explanation:
The reason is that the both have agreed on the terms of payment and includes the payment in shirt which is a consideration that has monetary value of $500 and hence is part of the total consideration of $1500 for the service of renovating kitchen. So once the clauses of the contract are accepted then it can not be revoked unless the other party is also willing to waive off the contract clause.
In this situation, the note is nonnegotiable because of the inclusion of payment only accepted in the form of $1000 money and $500 in the form of custom-made shirts.
