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

Assertion A: According to de-Broglie, the wavelengths associated with electrons and other subatomic particles can be detected experimentally.

Reason R: The wavelength associated with any material particle is directly proportional to its mass. In the light of the above statements, choose the correct answer from the options given below:

A
A is true but R is false.
B
A is false but R is true.
C
Both A and R are true and R is the correct explanation of A.
D
Both A and R are true but R is NOT the correct explanation of A.
