Under 46 CFR Part 199, each survival craft stowage arrangement must allow two crew members to complete preparations for embarkation and launching in less than how many minutes?

Why C is correct

46 CFR §199.130(a)(5) requires that each survival craft be sufficiently ready for use so that two crew members can complete preparations for embarkation and launching in less than 5 minutes. The 10-minute and 30-minute figures appear elsewhere in Part 199 as launching time limits for different vessel classes, not as the preparation standard.
