A.Droughts

Explanation:

Droughts are prolonged periods of water shortage, which can significantly reduce the availability of water for plants, animals, and entire ecosystems. Extended drought conditions can lead to the death of vegetation, loss of water resources, and the disruption of food and water sources for wildlife. This can result in long-term reductions in biodiversity as species that cannot adapt to the dry conditions may become endangered or extinct.

Here’s why the other options are less likely to cause long-term reductions in biodiversity due to water shortages:
