SOLUTION — Given equation can be rewritten as
$ 4(x-3)^2+16(y-1)^2=53 \\$
$\Rightarrow \frac{(x-3)^2}{53 / 4}+\frac{(y-1)^2}{53 / 16}=1 \\$
$\text { Here, } a^2=53 / 4, b^2=53 / 16 \\$
$\therefore e=\sqrt{1-\frac{b^2}{a^2}}=\sqrt{1-\frac{4}{16}}=\frac{\sqrt{3}}{2}$
So, The correct option of this question will be (C).
