Explanation
First simplify inside the parentheses:
39 – (25 – 17) = 39 – 8 = 31
You could also distribute the minus sign to get 39 – 25 + 17 if you prefer. Quantity B is equal to –3, so Quantity A is greater. If you noticed right away that the minus sign would distribute in Quantity A but not Quantity B, you could have picked (A) without doing any arithmetic.
Hence option A is correct!
