Ozone depletion is associated with which agricultural impact?

Explanation:
Ozone depletion lets more UV-B radiation reach the Earth's surface, and that extra UV-B directly stresses plants. UV-B can damage DNA, proteins, and chlorophyll, disrupt photosynthesis, and increase reactive oxygen species, which slow growth and cause leaf injury. All of this tends to reduce crop growth and yields, especially in sensitive species. That’s why the agricultural impact is decreased crop yields. The other options don’t fit because UV-B stress from ozone loss doesn’t improve yields, and it does have measurable effects—there is not a universal “no effect” or a situation where drought resilience is enhanced simply due to ozone depletion.
