The correct answer is sarcomere.
A sarcomere refers to the fundamental unit of striated muscle tissue. It is the reiterating unit between the two Z lines. The skeletal muscles comprise tubular muscle cells known as muscle fibers or myocytes that are produced in the procedure called myogenesis.
When the muscle fibers of a motor unit attain an impulse, it instigates a response in each sarcomere between the myosin and actin filaments. This response leads to a start of a contraction and the sliding filament theory.

Answer:
The correct answer will be option-C.
Explanation:
Hypothalamus is a part of the brain which controls many important functions of the body by producing hormones.
When the amount of water gets reduced in the blood, it leads to a change in the osmolarity which can be easily detected by the osmorecpetors present in the neurons of the hypothalamus.
In response, neurons secrete Anti-diuretic hormone in the blood which acts in the tubules of the kidney where they help in re-absorption of the water from the body.
Thus, Option-C is the correct answer.
