Block pricing in Salesforce CPQ is used when a fixed price applies to a quantity range, as in this tiered pricing scenario (e.g., $1,800 for 6-10 licenses). Option A sets the Pricing Method to "Block" on the Product, enabling this model. Option E involves creating Block Pricing records for each tier (e.g., 1-5 = $1,000), defining the fixed prices. Option B (Non Discountable = True) ensures no further discounts apply, meeting the requirement. Option C (Fixed Price) applies a single price regardless of quantity, not tiered pricing. Option D (Slab Discount Schedule) is for percentage-based discounts, not fixed block prices. Salesforce CPQ documentation validates this setup for block pricing.
