What is the result?

    Correct Answer: A

    The result prints the updated prices for both products. The code first creates a list of products with initial prices of 1000 and 2000. Then, it applies a Consumer function to each product in the list, increasing each price by 100. Finally, it prints out each product's updated price. Therefore, The prices are updated from 1000 to 1100 for the TV and from 2000 to 2100 for the Refrigerator. Thus, the output is 'TV Price: 1100 Refrigerator Price: 2100.'
