Which risk increases when a spacecraft's molecular sieve malfunctions?

A)Increased condensate accumulation and filter blockage
B)Reduced spacecraft skin embrittlement resistance
C)Compromised thermal radiation dissipation performance
D)Accelerated solar panel electron degradation

💡 Explanation

Increased condensate occurs because a malfunctioning molecular sieve decreases water vapor adsorption, resulting in condensate accumulation and potential filter blockage; therefore filter blockages increase, rather than embrittlement, radiation, which require different failure modes such as thermal loading.
