Answer: Diploid; 2n
Explanation:
In many species, there are two representatives of each chromosome. In such species, the characteristic number of chromosomes is called the DIPLOID number. It is usually symbolized as 2n.
The two basic sets of chromosomes is called Homologous chromosomes, being two, it is called DIPLOID NUMBER (if one, it is Haploid number) and symbolized by 2n.

Answer:
The correct answer is option - d. Production of primary spermatocytes.
Explanation:
The accessory cells or supporting cells present within the seminiferous tubules of reproductive system termed as the Sertoli cells. They play various roles in the body and reproductive system.
Sertoli cells make blood-testis barrier in adjacent Sertoli cells in the seminiferous tubules. These cells secrete different types of enzymes and hormones such as inhibin which are also secreted by ovary and placenta in females. Sertoli cells produce seminiferous tubular fluid to provide nutrition to the sperm. Apoptotic germ cells are timely eliminated by these cells.
Thus, the correct answer is option D. Production of primary spermatocytes.
