Question

Given below are two statements. One is labelled as
Assertion A and the other is labelled as Reason R.
Assertion A : Two identical balls A and B thrown with same velocity ‘u’ at two different angles with horizontal attained the same range R. If A and B reached the maximum height h1 and h2 respectively, then $\mathrm{R}=4 \sqrt{\mathrm{~h}_1 \mathrm{~h}_2}$
Reason R: Product of said heights. $h_1 h_2=\left(\frac{u^2 \sin ^2 \theta}{2 g}\right) \cdot\left(\frac{u^2 \cos ^2 \theta}{2 g}\right)$
Choose the CORRECT answer :

Select the correct option:

Both A and R are true and R is the correct explanation of A.

Both A and R are true but R is NOT the correct explanation of A.

A is true but R is false

A is false but R is true
