Let's plug in a nice even value for G.
The easiest will be G = 0.
We get:
(A) \(3(0) + 2 = 2 \). No good; we want an ODD value.
(B) \(0^2 = 0\). No good; we want an ODD value.
(C) \(\frac{0}{2} = 0 \). No good; we want an ODD value.
(D) \((0 - 3)^2 = 9\) Perfect!
(E) \(5(0) + 2 = 2\). No good; we want an ODD value.
Answer: D
