Assertion (A): The charge to mass ratio of particles in canal rays depends on the nature of the gas present in the discharge tube. Reason (R): Canal rays are positively charged gaseous ions derived from the gas inside the discharge tube. In the light of the above statements, choose the correct answer from the options given below:

1. Both (A) and (R) are true and (R) is the correct explanation of (A).
2. Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
