Solution

The correct option is A Centriole
Organelles are defined as specific subcellular components found inside a cell which are capable of performing a specific functions. They include mitochondria, lysosomes, centrosome with centrioles, endoplasmic reticulum, etc.

The spermatozoan delivers its nucleus containing the haploid set of chromosomes obtained from the male parent. Apart from the paternal half of the chromosomes, it also contributes the centrioles to the zygote for its cleavage division. Centrioles are not present in the oocyte, but the oocyte contributes other organelles such as mitochondria, lysosomes, and smooth endoplasmic reticulum.
