Solution

The correct option is B False
$x^{2} + 2 \sqrt{x} - 3 = 0$

$\Rightarrow$ A quadratic equation is an equation of the second degree, meaning it contains at least one term that is squared.

$\Rightarrow$ Comparing equation $x^{2} + 2 \sqrt{x} - 3 = 0$ with standard form of quadratic equation $a x^{2} + b x + c = 0$ .

$\Rightarrow$ So, here we do not get $b$ term

$∴$ The equation $x^{2} + 2 \sqrt{x} - 3 = 0$ is not quadratic equation.
