Which are sensitive to SO2 pollution?
Mosses
Algae
Lichen
Ferns
C.
Lichen
Lichens are sensitive to SO2 environment. They can not grow in sulphur dioxide pollutated area. So, lichens are called pollution indicating plants.
Mosses are sensitive to acidity and Nitrogen.
Algae are sensitive to some pollutants. Their metabolism is sensitive to the variation of environmental and natural disturbances.
