Answer:
Rock Group and Costume Shop
Under this arrangement the rock group is the
d. assignor.
Step-by-step explanation:
The rock group, as the assignor, is the entity that transfers its property rights or its powers to payment to Costume Shop. The Costume Shop is the assignee because it is the entity to which property rights or powers to payment of the rock group are transferred. Under the performance contract, the rock group can also be described as the delegator while the Costume Shop is the delegatee. However, under payment terms, the rock is the assignor while the Costume Shop is the assignee.
