Which of the following is a common agricultural pollutant?

Fertilizers are a common agricultural pollutant because they are widely used in farming to enhance plant growth by providing essential nutrients like nitrogen, phosphorus, and potassium. When rain falls, these fertilizers can run off into nearby waterways, leading to nutrient pollution. This excess nutrients can trigger harmful algal blooms, which deplete oxygen in the water, adversely affecting aquatic life and water quality.

In contrast, plastic bags, household waste, and construction debris are typically associated with urban and industrial pollution, rather than agricultural practices. While they can certainly impact the environment, they do not originate from agricultural activities, which is the specific focus of identifying common agricultural pollutants.
