We can solve this question using matching operations

Given:
Quantity A: y/(y + 17)
Quantity B: y/(y + 11)

Since y is POSITIVE, we can safely divide both quantities by y to get:
Quantity A: 1/(y + 17)
Quantity B: 1/(y + 11)

Since y is POSITIVE, we know that (y + 17) is POSITIVE, so we can safely multiply both quantities by (y + 17) to get:
Quantity A: 1
Quantity B: (y + 17)/(y + 11)

Likewise, we can safely multiply both quantities by (y + 11) to get:
Quantity A: y + 11
Quantity B: y + 17

Subtract y from both quantities to get:
Quantity A: 11
Quantity B: 17

Answer: B
