Direct Answer

Option B: Incorrectly measured Ullages/ Temperatures/ densities, Tanks filled but not taken into account, The contents of pipelines not allowed for, Incorrect temperatures or densities, Cargo mistakenly loaded on top of ballast and Cargo lost in the shore installation.

Gross mismatches in cargo figures can stem from multiple sources: inaccurate ullage/temperature/density readings, unrecorded tank fillings, uncompensated pipeline volumes, incorrect temperature/density data, cargo loaded over ballast, or losses at shore facilities, all contributing to discrepancies.

All Options
