NEET Physics Question - Unit And Dimensions

Assertion (A): Light year and wavelength have same dimensions.

Reason (R): Light year represent time while wavelength represent distance.

Both (A) & (R) are true and the (R) is the correct explanation of the (A)

Both (A) & (R) are true but the (R) is not the correct explanation of the (A)

(A) is true but (R) is false

Both (A) and (R) are false

Both light year and wavelength represent distance and have the dimension \([L]\). Since light year represents distance and not time, R is false.
