← TechnologyWhich outcome occurs when cryogenic fuel tank vent valves experience icing?
A)Over-pressurization and potential tank rupture✓
B)Increased fuel pump cavitation risk
C)Decreased combustion efficiency in engines
D)Elevated boil-off rate accelerating fuel loss
💡 Explanation
Cryogenic tank icing causes valve malfunction because ice obstructs the **valve sealing mechanism**, preventing proper venting; therefore, pressure increases leading to structural failure, rather than limited pump performance like cavitation or altering combustion profiles under normal valve control.
