Hint: An egg is approximately 30 times as wide as a sperm cell, like a sperm cell, the egg comprises a nucleus with half the number of chromosomes as other body cells. As for proportion, the egg is greater than the sperm gamete.

Complete Answer:
Let us find the correct answer:
Option (A) Chromosomes: Sperms, generated by males, encompass a 23rd chromosome that is either an X chromosome (female) or the analogous Y chromosome (male), giving rise to each sperm cell either female or male.
- Whereas female gametes constitute a 23rd chromosome that is XX. During fusion or fertilization gametes from the sperm combine with gametes from the egg to mold a zygote. The zygote encloses two sets of 23 chromosomes, for the mandatory 46.

Option (B) Centrioles: Evolving sperm cells and oogonia have two functional centrioles or diplosomes in their centrosomes, implying the typical "9+0" association of microtubule triplets that are familiar to somatic cells.

Option (C) Cytoplasm: In the maximum of the higher plants and animals incorporating humans, the male gamete is small and motile, whereas, the female gamete is large and immobile. The female gamete provides both the genetic material as well as cytoplasm during zygote formation as correlated to the male gamete does not provide cytoplasm but provides only half the genetic complement. Therefore, major cell organelles like mitochondria and chloroplasts indicate cytoplasmic or maternal inheritance structures.

Option (D) Mitochondria: The developed egg cell, or oocyte, encompasses the massive quantity of mitochondria among human cells, varying from 100,000 to 600,000 mitochondria per cell, but each mitochondrion encloses only one copy of mtDNA.
Whereas the midpiece of the sperm is stored with mitochondria. Mitochondria are organelles in cells that generate energy. Sperm use the energy in the midpiece to proceed.

Thus, the correct answer is option C.

Note: These gametes include a distinctive copy of half the genes of the parent source. When fertilization happens, an egg fuses and mixes genetic material with a sperm to create a full set of chromosomal DNA, with 23 pairs of chromosomes.
