What is one benefit of using plastic produce bags?

Using plastic produce bags helps maintain humidity and extend freshness, making option B the correct choice. These bags trap moisture, creating a microenvironment that reduces dehydration and oxidation of fruits and vegetables. This is particularly important for produce that is sensitive to drying out, as maintaining the right humidity levels can significantly prolong the shelf life and quality of the items stored within them.

Other options do not accurately reflect the benefits associated with plastic produce bags. While biodegradable bags may be more environmentally friendly, traditional plastic bags are not typically biodegradable. The assertion that plastic bags decrease the weight of the produce does not account for the fact that the bags themselves do add weight. Lastly, while there are instances where paper bags might be more expensive, many plastic bags are often less costly, contradicting the notion that they are more costly than paper bags.
