A Correct answer
Explanation

The IF-ELSE structure executes sequentially. Since amount is initialized to 7, the condition 'amount = 5' is false, but 'amount = 7' is true, so word becomes 'DOG'. The later assignment 'amount = 5' only changes the amount variable, not word. The final values are amount=5 and word='DOG'.
