What are primary pollutants?Airborne primary contaminants are introduced directly. They consist of heavy metals, volatile organic compounds (VOCs), particulates, nitrogen oxides, sulfur oxides, and carbon oxides.
Primary pollutants result in secondary pollutants. They consist of chemical evaporation, ground-level ozone, and photochemical smog.
A pollutant with a natural origin is one that was produced by elements found in nature, such as ozone produced by photochemistry, sea salt particles, volcanic dust, and fibers from trees, among others.
Therefore, the correct option is A) Primary Pollutant.

A cell is the fundamental, structural, and functional unit of all living things. Plant cells do not have lysosomes or centrosomes, whereas animal cells do (or a pair of centrioles).
What is Plant cells?A plant cell is a eukaryotic cell with a true nucleus and organelles that perform specific functions. However, some organelles found in plant cells differ from those found in other eukaryotic cells. Organelles, cytoplasmic structures, cytosol, cell membrane (also known as plasma membrane), and cell wall are all components of a typical plant cell structure.Plastids, nucleus, mitochondria, endoplasmic reticulum, and Golgi apparatus are plant cell organelles. The plant cell is the fundamental unit of all plants. Plant and animal cells are both eukaryotic, which means they have a membrane-bound nucleus and organelles.
