On vessels with AC distribution systems, which of the following statements represents the most difficult problem involved in obtaining a DC potential suitable for use by computer components?

Correct Answer: Option D — The voltage must be rectified and made ripple free.

Converting shipboard AC power to clean DC power for sensitive electronic computers requires robust rectification followed by extensive filtering networks. Removing AC ripple is critical because voltage fluctuations cause erratic computer operation, memory corruption, and failure of sensitive solid-state components.
