Match List-I with List-II.
List-IList-II
(A) Meter (L)I. hcG\sqrt{\dfrac{hc}{\mathrm{G}}}
[6pt] (B) Second (S)II. Ghc5\sqrt{\dfrac{\mathrm{G}h}{\mathrm{c}^5}}
[6pt] (C) Kilogram (M)III. K2L2c3Gh\sqrt{\dfrac{\mathrm{K^2L^2c^3}}{\mathrm{G}h}}
[6pt] (D) Kelvin (K)IV. Ghc3\sqrt{\dfrac{\mathrm{G}h}{\mathrm{c}^3}}

where h (Planck's constant), G (gravitational constant) and c (speed of light in vacuum) are taken as fundamental units.

Choose the correct answer from the options given below:

  1. (1)A-II, B-IV, C-I, D-III
  2. (2)A-IV, B-II, C-I, D-III
  3. (3)A-IV, B-I, C-II, D-III
  4. (4)A-III, B-I, C-II, D-IV
We corrected a printing error in the original paper

Source printed “c (speed of light in vacuum) as fundamental units” (verb missing).
