Explanation:

Volcanic eruption is a natural phenomena which occurs due to internal disturbances of the earth crust. This results in an explosive event which liberates ash, gases and hot magma with pressure from a volcanic vent. This explosive event with the liberation of hot gases like water vapor, carbon dioxide, carbon monoxide, sulfur dioxide and nitrous oxide along with liberated magma. Organisms which are in close proximity of the volcanic vent like trees, mosses, algae, grasses and bushes will be burned out with the hot magma liberated from a volcanic vent.

Therefore, on the basis of the above explanation, d.  all types of organisms in fewer numbers is the correct option.
