Explanation:

Universal Containers wants to sell a specific combination of products (with set quantities) as a single sellable product — this is the definition of a Product Bundle in Salesforce B2C Commerce.

🔹 Breakdown of the scenario:
"The Basics" is a composite product made of:

1 x Model 103 container
5 x Model 611 container
3 x Model 201 container

All the component products already exist in the catalog.
The goal is to create a new product ID that represents this combination for sale.
➡️ This use case exactly matches the Product Bundle functionality.

📌 Steps in Business Manager:
Go to Merchant Tools > Products > Products
Click "New" to create a new product (ID: e.g., the-basics)
Set the new product’s basic info (name, type = Bundle, availability, etc.)
Go to the Product Bundles tab
Add the three existing products and their quantities:
1 x Model 103
5 x Model 611
3 x Model 201

❌ Why the other options are incorrect:
A. In the Product Bundles module, create a bundle named “The Basics”
🔴 There is no standalone "Product Bundles" module in Business Manager.
Bundling is handled through the Product module, under a product's "Product Bundles" tab.

C. In the Products module, create a product named “The Basics” and add the products to the Product Sets tab
🔴 Product Sets are for grouping products for search, sorting, or merchandising, not for selling a combination as a single SKU.
You cannot define quantity or sell as one unit using Product Sets.

D. In the Product Sets module, create a product set named “The Basics”
🔴 Same issue as C — Product Sets are not sellable composite products.
They are typically used for visual grouping or filters, not as a single product offering.

🧠 Summary:
When creating a sellable combination of products with specific quantities under a unique product ID, you need to use a Product Bundle — which is done within the Product module, under the Product Bundles tab.
