In the network shown in the below figure, points \( A, B \), and \( C \) are at potentials of \( 70 \mathrm{~V} \), zero, and \( 10 \mathrm{~V} \), respectively. Then
(A) The potential of point \( D \) is \( 40 \mathrm{~V} \)
(B) The currents in the sections \( A D, D B \), and \( D C \) are in the ratio \( 3: 2: 1 \)
(C) The currents in the sections \( A D, D B \), and \( D C \) are in the ratio of \( 1: 2: 3 \)
(D) The network draws a total power of \( 200 \mathrm{~W} \)
