Assertion: Electrons are ejected from a ...

Assertion: Electrons are ejected from a certain metal when either blue or violet light strikes the metal surface. However only violet light cause electron ejection from a second metal.
Reason: The electrons in the first metal requires less energy for ejection.

A

If both assertion and reason are true and reason is the correct explanation of assertion

B

If the assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If assertion is false but reason is true.
