Classification of Elements and Periodicity in Properties

89684 Assertion: Electrons are ejected from a certain metal when either blue or violet light strikes the metal surface. However, only violet light causes electron ejection from a second metal.
Reason: The electrons in the first metal require less energy for ejection.

1 If both Assertion and Reason are true and the Reason is a correct explanation of the Assertion
2 If both Assertion and Reason are true but Reason is not a correct explanation of the Assertion
3 If Assertion is true but the Reason is false
4 If both Assertion and Reason are false
