How is a price group dynamically set?
A . By overriding the ccLogicProductPrice class
B . By using contract pricing
C . By extending the ccApiPriceList API
D . By extending the cc_hk_priceing hook

Answer: D

Explanation:

A price group can be dynamically set by extending the cc_hk_pricing hook. This hook allows modifying the price group based on various factors, such as the user, cart, product, or storefront. For example, the hook can apply a different price group for a specific product category or for a specific user segment.
