A single B-type spermatogonium produces 8 sperms via the meiosis process. As each spermatogonium has 2 spermatocytes and each spermatocyte undergoes meiosis to produce 4 sperm.
The process of producing male gametes from the spermatogonium is known as spermatogenesis (proliferative cells that give rise to sperm cells).
Meiotic cell division is a necessary step in the process of spermatogenesis (reductional cell division).
One spermatogonium can produce 512 spermatids after five meiotic divisions of each kind of spermatogonium, which results in the development of 32 type B spermatogonia, 64 primary spermatocytes, and 32 type B spermatogonia from one spermatogonium.
Consequently, one type B spermatogonium can undergo mitosis to produce two primary spermatocytes (equational division).
Additionally, each spermatocyte undergoes meiosis to produce 4 sperm.
As a result, one B-type spermatogonium can yield 8 sperm.

I believe the answer is C.
Answer: 1. Organ system
2. Organ
3. Cell
4. Tissue
Explanation:
1. An organ system is a combination of two or more organs which are responsible for the conduction of a vital function in the body. For example, nose, phyrnx, larynx, and lungs they are responsible for the process of respiration.
2. An organ is a group of specialized tissues that combined and adapted together to perform a specialized function in an organism.
3. A cell is a basic unit of life. It is the small unit which forms the structural basis of the organism. The organisms may vary in complexity depending upon the number of cells and the functions performed by these cells.
4. A tissue is a group of cells. These cells combine together to perform a function that is common to all. The cells in tissues have a common origin.
