Final answer:
The question is about comparing two numbers and subtracting them based on whether one is greater than the other.
Step-by-step explanation:
Given two numbers, a and b, if a > b, then the value of a - b is printed. If a is not greater than b, then the value of b - a is printed. This can be represented as:
a) a > b
b) a - b
c) b > a
d) b - a
For example, if a = 5 and b = 3, a - b = 5 - 3 = 2. Therefore, the correct answer would be b) a - b.
