Multiple Choice

Eliminate the parameter and write the corresponding rectangular equation whose graph represents the curve.​ $\begin{array} { l } x = 4 \cos \theta \\y = 2 \sin \theta\end{array}$ ​

A) ​ $$\frac { x ^ { 2 } } { 4 } + \frac { y ^ { 2 } } { 16 } = 1$$
B) $\frac { x ^ { 2 } } { 16 } + \frac { y ^ { 2 } } { 4 } = 1$
C) $$y = \frac { x } { 4 }$$
D) $y = \frac { x } { 2 }$
E) ​ $\frac { x ^ { 2 } } { 16 } - \frac { y ^ { 2 } } { 4 } = 1$
