According to 46 CFR §199.130, a liferaft without an indicated maximum stowage height on its container must be stowed no more than what height above the waterline with the vessel in its lightest seagoing condition?

Why A is correct

46 CFR §199.130(c)(2) states that a liferaft without an indicated maximum stowage height must be stowed not more than 18 meters (59 feet) above the waterline with the vessel in its lightest seagoing condition. The 4.5-meter figure relates to launching appliance requirements, and 2 meters is the minimum stowage height above the waterline.
