what do you mean by cell ?
Cell is the basic unit of any living organism present in animal, plant, microbes etc; Bacteria are unicellular organism where as higher eukaryotic organisms are multicellular in nature like plants and animal cell.
Prokaryotic cells are the most simplest form of cell which have a cell membrane, cytoplasm, ribosomes where protein synthesis occur, and nucleoid genetic material are present, most of bacteria have cell wall, reproduce by binary fission.
The eukaryotic cells have all the organelles like it has outer covering cell membranes, cytoplasm, ribosomes, and nucleus, rough endoplasmic reticulum for protein assembly, smooth endoplasmic reticulum, Golgi apparatus for protein sorting and exporting.
It has mitochondria the power house, a cytoskeleton for structure of the cell and communication, and lysosomes or peroxisomes for digestion of waste, vacuoles for water storage, chloroplasts for photosynthesis.
Thus option A is correct.

please mark brainliest.
The functional cell of the nervous system is neurons.
What is a nervous system?The nervous system is the main controlling system of the living body. It consists of the brain and the spinal cord. The nervous system is divided into two parts, the central nervous system, and the peripheral nervous system.
Neurons are the cells of the nervous system. The cells are branch-like structures like the roots of a plant, they contain absorb the information using electrical impulses and transport it into different areas of the brain.
The central nervous system contains the brain and the hypothalamus, and the peripheral nervous system contains all the neuron cells. The neuron cells' function in the peripheral system is to collect the signals and information and to send it to the central number system, which contains the brain for processing.
Therefore, neurons are the functional cell of the nervous system.
