" The single cell which divides again and again and is the beginning of life is:

Correct option is C

The zygote is the single cell formed when a sperm cell fertilizes an egg cell during reproduction. This zygote contains the combined genetic material from both parents and is the starting point of life. After its formation, the zygote undergoes a series of mitotic cell divisions known as cleavage, eventually leading to the formation of a multicellular organism.
· The zygote is unique because it has the potential to develop into a full organism, beginning with rapid cell division and specialization.
Information Booster:
· The zygote represents the first stage of embryonic development. It divides continuously and differentiates into various cell types, tissues, and organs, ultimately leading to the formation of a new individual.
Additional Knowledge:
· DNA (a): Deoxyribonucleic acid, the molecule that carries genetic information, but it is not a cell itself.
· Autosome (b): One of the chromosomes that is not a sex chromosome; it does not refer to a single cell.
· Chromosome (d): A structure within cells that contains DNA, responsible for transmitting genetic information, but it is not the beginning of life itself.
