Explanation:

2. The correct answer is A.

Explanation:

Let’s break down the expression a + b * c / a - b step-by-step according to the order of operations:

  1. Multiplication and Division are performed first from left to right:
    • b * c = 10 * 15 = 150
    • 150 / a = 150 / 5 = 30
  2. Addition and Subtraction are performed next from left to right:
    • a + 30 = 5 + 30 = 35
    • 35 - b = 35 - 10 = 25

So, the value of result is 25, and the program prints 25.
