Answer 1

The correct option is D All of these

Air is the most important component for the survival of life on Earth. We breathe in air. The oxygen present in air is required for respiration of living beings. The carbon dioxide present in air is essential for the green plants to manufacture their own food by the process of photosynthesis. Water vapour present in the air provides moisture and also helps in predicting climatic conditions of a particular area.
