Make the correct pair of food packaging technology given in Column I with operating principle or description in Column II.

Column I	Column II
P. Aseptic packaging	1. Control of the concentration of O₂ and CO₂ inside the package
Q. Active packaging	2. Create a skin tight package wall
R. Modified atmosphere packaging	3. Independent sterilization of food and packaging material and packaging under sterile environment
S. Vacuum packaging	4. Makes non-passive contribution to product development

Answer: A

The match is P-3, Q-4, R-1, S-2.

Aseptic packaging sterilizes the food and the packaging separately and fills them in a sterile environment.
Active packaging contains components such as oxygen scavengers or antimicrobials that take a non-passive part in keeping the product.
Modified atmosphere packaging sets the concentrations of O₂ and CO₂ inside the pack.
Vacuum packaging removes air so the film pulls tight around the product, forming a skin-tight wall.

The other options confuse vacuum packaging with active packaging, or modified atmosphere with aseptic packaging.
