The Correct Option is A
Solution and Explanation
Centrosome is a complex structure consisting of two centrioles and centrosphere. It has a cylindrical structure without limiting membrane. It consists of nine triplet fibres, each consisting of three secondaiy fibres or tubules. These are enclosed in amorphous matrix. Centrosome separates into a pair of centrioles. The centrioles take part in formation of basal bodies and mitotic spindle. They are found in lower plants and most of the animals but these are absent from the cells of prokaryotes, diatoms, yeast and most of the higher plants.

Cell: The Unit of Life
- A cell is derived as the functional and structural unit of life. Every cell is surrounded by a cell membrane that dissects the external and internal environments of the cell. The interior environment of a cell is called the cytoplasm.
- It carries cellular machinery and structural elements. The nucleus is present in the center of the cell, which includes all the hereditary information of an organism. Some of the molecules present in the cell are protein, carbohydrates, starch, and sugar.
