We need to know which operation \(#\) signifies

Statement 1: this implies that \(#\) is multiplication because for any other operation \(\frac{1}{2}#\frac{1}{2}\) will not be equal to \(\frac{1}{4}\). Hence Sufficient

Statement 2: here \(#\) can be multiplication, in that case \(3#2=6\)

or \(#\) can be subtraction, in that case \(3#2=1\). Hence no unique value. Insufficient

Option A
