Under 46 CFR §28.545, when a fishing vessel uses lifting gear, the angle of intersection of the heeling arm curve resulting from the lifting moment and the righting arm curve must not exceed which value?

Why C is correct

46 CFR §28.545(c) states that the angle of intersection of the heeling arm curve resulting from the lifting moment or the moment of fishing gear and the righting arm curve must not be at an angle of more than 10° (0.17 radians). The other values appear elsewhere in the stability criteria but do not apply to this specific intersection requirement.
