Question Statement:
The fundamental operational distinction between Controlled Atmosphere (CA) storage and Modified Atmosphere (MA) storage is that:
Options:
- (A) CA storage dynamically monitors and actively adjusts gas concentrations ($O_2, CO_2, N_2$) continuously, whereas MA relies on passive equilibrium between produce respiration and film permeability
- (B) CA storage operates at frozen temperatures while MA operates at room temperature
- (C) MA storage utilizes toxic ethylene oxide gases while CA storage uses pure steam
- (D) CA storage is strictly applied to grains while MA is strictly applied to liquid milk
