Compatibility of fuel is easily checked onboard ship to insure that serious problems do not result. What statement concerning fuel incompatibility is true?

AIncompatible fuels, if allowed to mix, have a tendency to form sludge, and therefore must not be blended.
BIncompatible fuels, if allowed to mix, have a tendency to separate out from one another, and therefore must be vigorously blended.
CIncompatible fuels, if allowed to mix, have a tendency to form sludge, and therefore must be vigorously blended.
DIncompatible fuels, if allowed to mix, have a tendency to separate out from one another, and therefore must not be blended.
AI Explanation

The correct answer is A) Incompatible fuels, if allowed to mix, have a tendency to form sludge, and therefore must not be blended. Explanation: Fuel compatibility is an important consideration on ships to avoid operational issues. Incompatible fuels, when mixed, can form sludge and gum deposits that can clog fuel systems and damage engines. The correct approach is to avoid blending incompatible fuels, as option A states, rather than trying to vigorously blend them (options B and C), which could still lead to sludge formation. Separating the fuels (option D) is also not the correct solution, as the fuels should not be allowed to mix in the first place.
