Get rid of the brackets from qty A by simplifying we get,
3-9+7 = 1
Since \(a > 1\) qty B is always greater than 4
3-9+7 = 1
Since \(a > 1\) qty B is always greater than 4

We can solve this question using matching operations
Given:
Quantity A: \(3 + (− 9) − (− 7)\)
Quantity B: \(4a\)
Evaluate Quantity A:
Quantity A: \(1\)
Quantity B: \(4a\)
Divide both quantities by 4 to get:
Quantity A: \(\frac{1}{4}\)
Quantity B: \(a\)
Since we're told that \(a > 1\), we can be certain that \(a > \frac{1}{4}\)
Answer: B
