Answer:
The correct answer would be a. They shrink as water moves from inside to outside the cells as a result of osmosis.
Osmosis refers to the movement of water from the region of high solvent or water concentration to the region of low solvent or water concentration.
In this condition, the concentration of water in a concentrated salt (hypertonic) solution would be less as compared to that of a red blood cell.
Thus, the water from inside the cell will move outside the cell. Consequently, the cell would shrink in size.

Answer:
These are Cowpers's gland.(Bulbo Urethral Gland)
Explanation:
These are small pea-sized glands at the base of the penis which connect each with the urethra through a short duct. It is thorough this ducts that secretion from each gland gets to the urethra.
They secretes thick alkaline fluids for lubrication of urethral and tip of the penis, for expulsion of left over urine, dead cells, mucous from the urethra for clean sperm passage.
The serrations also neutralise the acidity of the urethral
