The correct answer is B.Walking to the store.

Walking instead of driving helps reduce pollution by lowering the amount of greenhouse gases and other pollutants emitted by vehicles. Cars and other forms of transportation are major sources of air pollution, including carbon dioxide (CO2), which contributes to climate change. Walking, on the other hand, produces no emissions and is a more environmentally friendly way to get around.

Here’s why the other options are less effective:

A.Driving to the store: This contributes to pollution, as vehicles emit harmful gases and particles that can degrade air quality and contribute to global warming.
