In the potential energy diagram of an organic molecule $\mathbf{X}$ rotating around one of its bonds, the points where the first derivative of the potential energy curve is 0 correspond to the following conformations $\mathbf{A\sim D}$:

The points where the first derivative of the potential energy curve is 0 correspond to four different energies $1\sim 4$ (with the lowest energy conformation as the zero point, unit $\mathrm{kcal}$): 0.00, +0.06, +1.39, +2.68.

Please match the conformation numbers with the energy numbers, and select the correct result from the following options.

Options: (A) All other options are incorrect (B) A-1 B-2 C-3 D-4 (C) A-3 B-2 C-1 D-4 (D) A-3 B-1 C-2 D-4 (E) A-2 B-1 C-3 D-4 (F) A-2 B-3 C-1 D-4 (G) A-1 B-2 C-4 D-3 (H) A-1 B-3 C-4 D-2 (I) A-1 B-4 C-3 D-2 (J) A-1 B-4 C-2 D-3

Answer with the single letter of the correct option (A-J). Think step by step, then end with "The answer is (X)".
