Explanation:

UC sells in USD, GBP, and EUR. The Support SKU is only available in USD and EUR. All correct Pricebook Entries have been created for USD and EUR.

When adding a product to a quote:
- Salesforce CPQ checks whether there’s a Pricebook Entry for that product in the quote’s currency.
- If yes → product appears in Product Selection and can be added at the Pricebook Entry’s List Price.
- If no → product is unavailable in Product Selection and does not appear at all.

Therefore:

✅ USD → Product has a Pricebook Entry, visible in Product Selection, can be added at List Price.
✅ EUR → Product has a Pricebook Entry, visible in Product Selection, can be added at List Price.
🚫 GBP → No Pricebook Entry, product is unavailable in Product Selection.

This matches option C.

❌ Why Other Options Are Incorrect:

A. USD: Product is unavailable… EUR: Product is unavailable…
→ Incorrect. USD and EUR have valid pricebook entries, so the product should be available.

B. GBP: Added to Quote with 0 List Price.
→ Incorrect. If there’s no Pricebook Entry, the product cannot be added at all and does not appear in Product Selection.

D. Error presented to user…
→ Incorrect. Salesforce CPQ simply hides the product if it’s unavailable in the pricebook for the quote currency. No error is shown to the user.

✅ Example Scenario:

- GBP Quote → user searches “Support SKU” → product does not appear in the list.
- USD Quote → user searches “Support SKU” → product shows up with proper price.
- EUR Quote → user searches “Support SKU” → product shows up with proper price.
