Two cables of copper are of equal lengths. One of them has a single wire of area of cross-section \( A \), while other has math xmlns=http://www.w3.org/1998/Math/MathML class=wrs_chemistrymn10/mn/math wires of cross-sectional area \( A / 10 \) each. Give their suitability for transporting A.C. and D.C.
(a) only multiple strands for A.C., either for D.C.
(b) only multiple strands for A.C., only single strand for D.C.
(c) only single strand for D.C., either for A.C.
(d) only single strand for A.C., either for D.C.
