The question is incomplete as it does not have the options which are:

A. Merocrine gland

B. Apocrine gland

C. Salivary gland

D. Holocrine gland

Answer:

D. Holocrine gland

Explanation:

Exocrine glands are the organs or the subcellular structures which secrete a substance which is excreted out of the body.

The exocrine glands are different from the endocrine glands as their secreted products are released out of the body which is not in the case of endocrine glands.

The wax is secreted by the sebaceous glands by the production of cells that break along the base of the garland with substance into the ductal system by the exocrine glands called Holocrine glands.

Thus, Option-D is the correct answer.

Holocrine glands will release whole broken open cells into their ductal system. These cells contain the stores of substance to be released by the gland. This method of secretion requires frequent cell turnover and replacement.

So were is the genetic material find in a prokaryotic cell
tiny-mole [99]
Endomembrane system -- not in prokaryotes
cytoskeleton -- a structural part of cytoplasm sometimes occurrent in prokaryotes
mitochondria -- not in prokaryotes 
nucleus -- if this is a "membrane-bound" nucleus, then definitely not in prokaryotes
cytoplasm -- this is the fluid that houses everything in the cell membrane
flagella -- little "tail" for locomotion, so no
cilia -- similar to flagella, little feelers usually for locomotion 
ribosomes -- these make protein using amino acids
chloroplasts -- not in prokaryotes
membrane -- just a casing surrounding a cell or organelle
organelles -- general word for the parts of a cell that perform various functions
cell membrane -- just the casing for the cell, not where genetic material's located
<span>nucleoid --- ding ding ding :-) this is it; a nucleoid is the genetic material which is loosely existing in the cytoplasm of a prokaryotic cell</span>
