1. You are testing a web application that allows users to SEARCH for products, VIEW product details, ADD products to a shopping cart, and place an ORDER.
You have prepared the following five test cases, which you want to execute according to their priorities:

You also identified the following logical dependencies between test cases:

- ADD functionality must be tested before ORDER functionality, as placing an order relies on the availability of accurate shopping cart information.
Which test case should be executed as the fourth one?
