• x is initialized to 1.
• Y is initialized to 0.
• The while loop condition is x < 10, which is initially true.
• Inside the while loop, Y is incremented by 1 on each iteration.
• However, x is never updated within the loop, so x remains 1 indefinitely.

This causes the loop to run infinitely because the condition x < 10 will always be true. The loop will never terminate, and Y will continue to increment indefinitely.

Therefore, the correct answer is:

D. An error occurs
