Solution

The correct option is D Both A and R are individually true and R is the correct explanation of A
L/R is the time constant used in calculative equations of circuit having resistance and inductance only.
and CR is the time constant used for circuits having resistance and capacitance only.
so Both L/R and CR are time constant so have same dimensions of time.
