Identify which requirement is functional and which requirement is non-functional from the following:

 Scenario:

Suppose you are going to build a furniture purchasing application. The furniture purchasing application allows users to search for and purchase various furniture items. The project is made up of a list of furniture items that are exhibited in various types and designs. The customer has the option of browsing these products by category. If a user chooses a product, he or she can add it to their shopping cart. The products can be seen in ascending or descending order based on their names and prices.

On each page of this application, an innovative floating cart will appear, displaying the products currently in the cart with the minimum information. First of all, the user must first register with the system before being allowed to view the products. The user can choose from three payment options: debit, credit card, or cash on delivery. The admin will add the products. In my orders column, the user can check his order history or the progress of the current order. Admin will be responsible to change the status of the orders. This application will help people to buy furniture online without wasting their precious time by going to the market.

As you see the above-mentioned scenario, keeping in view the major types of Software Requirements for this application, you are required to identify which requirement is functional and which requirement is non-functional from the following:
