Direction : Question number 89 contain Statement-1 and Statement-2. Of the four choices given after the statements, choose the one that best describes the two statements.
Statement-1: When ultraviolet light is incident on a photocell, its stopping potential is `V_(0)` and the maximum kinetic energy of the photoelectrons is `K_(max)`. When the ultraviolet light is replaced by X-rays. Both `V_(0)` and `K_(max)` increase.
Statement-2: Photoelectrons are emitted with speeds ranging from zero to a maximum value because of the range of frequencies present in the incident light.

A

Statement-1 is true, Statement-2 is false.

B

Statement-1 is true, Statement-2 is true , Statement 2 is the correct explanation of Statement-1.

C

Statement-1 is true, Statement-2 is true, Statement 2 is not the correct explanation of Statement-1.

D

Statement-1 is false, Statement-2 is true.
