Answer:

B. The dust and ash would block  sunlight, triggering climate  change.

Explanation:

If such an event as a nuclear war should cause large amount of dust and ash in the atmosphere, this will trigger climate change.

Dust and ash can lead to severe consequences on the global climatic pattern.

  • The rising dust and ash will block out sunlight and electromagnetic radiation from reaching the earth surface.
  • The earth will become abnormally cold as the source of the earth's heat is cut off.
  • This will lead to freezing of water bodies and more cold-inclined world climate.
