Final answer:
To define a property for the delivery method options Standard, Premium, or Next Day in a data model, a Value List should be used to hold these predetermined choices(option c).
Step-by-step explanation:
To capture the delivery method for a purchase request with options such as Standard, Premium, or Next Day in a data model, you need a way to list these predefined options.
The correct approach would be to use a Value List. A Value List is a data structure used to hold a simple list of values, where each entry in the list corresponds to a possible option for the delivery method. Therefore, you would define the delivery method property as a Value List with the entries 'Standard', 'Premium', and 'Next Day'.
