Solution

The correct option is B

e = $\frac{\sqrt{3}}{2}$

$\frac{1}{2}$ ab=16

$\Rightarrow$ ab=32

$b^{2}$ = $a^{2} (1 - e^{2})$

$b^{2}$ = $a^{2} (1 - \frac{3}{4})$ = $a^{2} (\frac{1}{4}) \Rightarrow 4 b^{2}$ = $a^{2}$

2b.b=32 $\Rightarrow b^{2}$ =16

a=2b,a=8

$\frac{x^{2}}{64} + \frac{y^{2}}{16}$ =1
