Best answer
$x = \sqrt{12 + x}$
$\implies x^2 = 12 + x$
$\implies x^2  x  12 = 0$
$\implies (x4) (x+3) = 0$
$\implies x = 4 \text{ or } x = 3$

X = 4 is taken because sum of positive terms can not be negative.

As a matter of humor maybe, in just several seconds you can also use GATE calculator for such question.
Just keep calculating till 23 times and you'll notice that the pattern is diverging toward one of the answers.
Cheers!
