Answer:
option a is correct.
Explanation:
Dimension of Resistance = Potential Difference / Current = ML2T-3A-1 / A = ML2T-3A-2
Dimension of Capacitance = Charge / Potential Difference = AT/ML2T-3A-1 = M-1L-2T4A2
Dimension of self Inductance [L]=[ϕ] / [I] = MT−2L2A−1 / A = ML2T-2A-2
a) Dimension of LC = ML2T-2A-2 * M-1L-2T4A2 = T2
b) Dimension of 1/ = (ML2T-2A-2 * M-1L-2T4A2 )-1/2 = T-1 = 1/T
c) Dimension of 1/ RC = 1/ (ML2T-3A-2 * M-1L-2T4A2) = 1 / T
d) Dimension of R / L = ML2T-3A-2 / ML2T-2A-2 = 1/ T
So answer is (a)
