Carbon is the atom, which is necessarily find in the living organism.
All the living organisms are made up of biomolecules. All the biomolecules are organic compounds. The substance cannot be consider as living, if it lacks nucleic acids. There are two types of nucleic acids DNA (deoxyribonucleic acid) and RNA (ribonucleic acid), both have a structure made up of carbon rings and chains.
Other than nucleic acids, proteins, enzymes, hormones etc are also made up of carbon. So, all the living cells, or dead remain of organism must have carbon atom.
Hence, the correct answer is option D. carbon.

Explanation:
Sensory receptor
Sensory receptor is known to
be a structure that responds to a physical stimulus in the environment which
can either be external or internal. Also, sensory receptor generally initiates the
same process of creating nerve signals and registering stimuli. Generally, sensory receptor usually serves as the front liner because they are in contact
with the stimulus.
The right answer is the kidney will regulate the blood pressure by the renin angiotensin aldosterone system.
The kidney plays a role of selective filtering of the blood. It allows the blood to get rid of its waste. But it also removes water and mineral salts that are in excess.
But the kidney also plays a dynamic role in increasing the pressure, by means of a system called "renin-angiotensin system" which is one of the most powerful natural hypertensives available to the body. Thanks to an enzyme he makes, renin, the kidney will turn a normal blood protein, angiotensinogen, into angiotensin, which causes the vessels in the body to contract and therefore increase blood pressure. This effect is manifested permanently in a disease which is the stenosis of the renal artery, that is to say the permanent narrowing of the caliber of this artery. The kidney, believing that the blood pressure decreases because of this narrowing, will permanently produce renin, which will cause an immediate increase in blood pressure.
