The correct answer is: D.Air pollution due to ash and gases

Volcanic eruptions release ash, sulfur dioxide (SO₂), carbon dioxide (CO₂), and other gases into the atmosphere. These substances can cause significant air pollution and impact air quality in the surrounding areas. The ash can also affect respiratory health, damage crops, and disrupt air travel.

The other options are less direct consequences of volcanic eruptions:

A. Eruptions do not "clean" the air; they massively pollute it by adding particulate matter an...
