उत्तर

A is true but R is false.

Explanation:

Refrigeration preserves food because cold temperatures significantly slow down the metabolic activity and reproduction of most bacteria. The reason is completely false because bacteria actually thrive and multiply rapidly in warm temperatures (the “Danger Zone” between 40°F and 140°F), not cold ones.
