The correct answer is d. Global warming.

Step 1: Understand the question. The question is asking about the cause of an increased intensity of the hydrological cycle with more frequent and intense floods and droughts.

Step 2: Analyze the options.

a. Photochemical smog: This is a type of air pollution that is not directly related to the hydrological cycle.

b. Acid rain: This is caused by the release of sulfur dioxide and nitrogen oxide into the atmosphere, which can harm water bodies and vegetation but does not directly affect the intensity of the hydrological cycle.

c. Nutrification: This is a process that increases the amount of nutrients in a body of water, often leading to excessive growth of algae and other organisms. It does not directly affect the hydrological cycle.

d. Global warming: This is the increase in Earth's average surface temperature due to rising levels of greenhouse gases. It leads to the melting of ice caps and glaciers, rising sea levels, and changes in precipitation patterns, all of which can intensify the hydrological cycle and lead to more frequent and intense floods and droughts.

Step 3: Choose the correct answer. Based on the analysis, the correct answer is d. Global warming.
