Answer 1

Hint: Blood is a bodily fluid found in humans and other animals that carries metabolic waste products away from cells while also delivering essential chemicals such as nutrition and oxygen. It is made up of blood cells suspended in blood plasma in vertebrates. Plasma is mainly water (92 percent by volume) and contains proteins, carbohydrates, mineral ions, hormones, carbon dioxide (plasma is the major medium for excretory product transfer), and blood cells themselves. Plasma makes about 55 percent of blood fluid. Albumin is the most abundant protein in plasma, and it regulates blood's colloid osmotic pressure.

Complete answer:
The degree of acidity or alkalinity in blood is an essential characteristic. The pH scale indicates the acidity or alkalinity of any fluid, including blood. The pH scale goes from 0 (very acidic) to 14 (extremely alkaline) (strongly basic or alkaline). A pH of 7.0, which is near the centre of the scale, is considered neutral. Blood is somewhat basic by nature, having a pH range of around 7.35 to 7.45. The pH of blood is usually kept close to 7.40 by the body.
The pH of a person's blood, as well as the amounts of carbon dioxide (an acid) and bicarbonate (a base), are measured by a doctor to determine their acid-base balance.
When the level of acidic chemicals in the body grows, blood acidity rises as well (through increased intake or production, or decreased elimination).
The body's level of basic (alkaline) substances decreases (through decreased intake or production, or increased elimination).
When the amount of acid in the body decreases or the amount of base in the body rises, blood alkalinity rises.
A rise in \[C{O_2}\] levels in the blood, resulting in a drop in blood pH. As a result, haemoglobin proteins will release their oxygen burden. A reduction in carbon dioxide, on the other hand, causes a rise in pH, which causes haemoglobin to absorb more oxygen. An increase in \[C{O_2}\] causes a drop in blood pH because carbon dioxide interacts with water to create carbonic acid. As a result, option C is the right response.

Note:
Automatic compensating mechanisms drive the blood pH back toward normal after each acid-base imbalance. In general, metabolic abnormalities are compensated for by the respiratory system, whereas respiratory disturbances are compensated by metabolic processes. The compensatory processes may initially restore the pH to a near-normal level. As a result, a large shift in blood pH indicates that the body's capacity to adapt is failing. Doctors look for and treat the underlying cause of the acid-base imbalance in such instances.
