In the standard \((x,y)\) coordinate plane, the graph of the equation \(y=3\sin{(2x+0.5\pi)}\) has what amplitude and period?

$$ \begin{array}{l c c} & \underline{\text{amplitude}} & \underline{\text{period}} \\ \text{A.} & 3 & \pi \\ \text{B.} & 3 & 2\pi \\ \text{C.} & 3 & 4\pi \\ \text{D.} & 6 & \pi \\ \text{E.} & 6 & 2\pi \\ \end{array} $$
