The Correct Answer is C
Acidosis is a condition where the blood's pH is lowered due to an excess of H+ in the body. This can occur due to metabolic causes, such as diabetes, kidney failure, ingestion of toxins, or respiratory causes, such as hypoventilation or lung disease. The body has several mechanisms to compensate for acidosis and restore the normal pH balance. One of them is to increase the rate and depth of breathing, which helps to remove CO2 from the body and reduce the formation of H2CO3.

Correct Answer is C
Explanation
The renin-angiotensin system (RAS) is a hormonal system that regulates blood pressure and fluid balance. When blood pressure is low, the kidneys secrete renin, which converts angiotensinogen into angiotensin I, which is then converted into angiotensin II by angiotensin-converting enzyme (ACE). Angiotensin II is a potent vasoconstrictor that narrows blood vessels and increases blood pressure. It also stimulates the release of aldosterone, which increases sodium and water retention and further raises blood pressure. When the RAS is overactivated, it can lead to a hypertensive crisis, which is a severe elevation of blood pressure that can damage organs and cause stroke, heart attack, or kidney failure.
