Solution

The correct option is A $I Q = \frac{M e n t a l a g e}{A c t u a l a g e} \times 100$
Intelligence Quotient helps to find out about a person's knowledge, his mental ability, judging ability and reasoning abilities etc.
The formula for finding out IQ is-
$I Q = \frac{M e n t a l a g e}{A c t u a l a g e} \times 100$
A person whose mental and actual age matches, his IQ is 100%. A person whose IQ is greater than 140 is supposed to be genius. Hence, the answer is option A.
