BSingle grab sample
CDrip method sample
DMixture of several grab samples
AI Explanation
The correct answer is A) Proportional extraction sample. A proportional extraction sample is the most reliable, accurate, and cost-effective option for shipboard fuel sampling. This method involves continuously extracting a small portion of the fuel flow, which provides a representative sample of the entire fuel tank. This ensures the sample accurately reflects the quality and composition of the fuel, as opposed to a single grab sample or drip method, which may not be representative of the entire tank. Regulations and industry standards generally recommend the use of proportional extraction sampling for accurate fuel testing and monitoring on vessels.
