AI Explanation

The correct answer is B) 14 AWG. According to 46 CFR Subchapter J, Section 111.60-3, replacement, instrument and control wiring in a switchboard must be a minimum of 14 AWG. This regulation ensures that the wiring used is sufficiently robust to handle the electrical loads and environmental conditions typically found in a switchboard. The other options, 12 AWG, 16 AWG, and 18 AWG, do not meet the minimum size requirement specified in the regulation.
