To ensure customers can only purchase products in increments of five, an Administrator must:

A. Connect the product to a Quantity Rule:This involves creating a Quantity Rule that specifies the allowed increments for product quantities and then associating this rule with the specific products.

D. Create Purchase Quantity Rules:This step involves defining the rules that govern purchase quantities, including setting the required increments, which in this case would be increments of five.

These steps ensure that when customers add products to their cart, they can only do so in the specified increments, aligning with the company's sales strategy and operational requirements.
