 Requirement:

Ensure a product priced as a Percent of Total has a minimum price of $100.

 Solution Steps:

Option A: Create a Price Book Entry of $100 to set the minimum price for the product.

Option D: Create a $0 Price Book Entry to handle scenarios where Percent of Total calculation would otherwise drop below $100.

 Why Other Options Are Incorrect:

B: The custom Percent_of_Total_Target_c field is not used for minimum pricing enforcement.

C: The Percent of Total Constraint field alone does not enforce minimum pricing.

 Salesforce CPQ Reference:

Percent of Total pricing and minimum price settings are described in CPQ Pricing Configuration ​.
