Answer & Explanation
Correct AnswerB. HVDC Transmission Line

Quick Explanation

In steady-state DC, line capacitance does not draw continuous charging current and current distribution is not subject to the AC skin effect. Therefore HVDC has essentially no charging current and no skin effect in normal steady operation.
