C Correct answer
Explanation

Food products are refrigerated because very low temperatures drastically reduce respiration rates in plant tissues, slowing down metabolic processes that cause spoilage. This preservation method maintains flavor, texture, and freshness by preventing the breakdown of sugars, starches, and other compounds that would otherwise occur through respiration and microbial growth at higher temperatures.
