- C. When the vessel is 70,000 gross tons or over and has two identical power units.

Why A is correct
46 CFR §58.25-10(f)(2) states that for a cargo vessel, no auxiliary steering gear need be fitted when the main steering gear with two or more identical power units is capable of meeting the rudder-movement standard of §58.25-10(c)(2) while all power units are operating. The 'any one not operating' standard applies to passenger vessels under §58.25-10(f)(1).
