Question

Given below are two statements: one is labelled as Assertion $A$ and the other is labelled as Reason $R .$

Assertion A: When a body is projected at an angle $45 °,$ its range is maximum.

Reason R: For maximum range, the value of sin $2 θ$ should be equal to one.

In the light of the above statements, choose the correct answer from the options given below:
