Assertion(A): Less production of ADH causes Diabetes insipidus.
Reasoning(R):It helps in the reabsorption of water, producing concentrated urine in small quantity Control and Coordination Choose the correct answer

Options

A. A is correct and R is the correct explanation of A.
B. A is correct and R is not the correct explanation of A.
C. A is correct and R is wrong.
D. A is wrong and R is correct.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Assertion (A)**: The assertion states that "Less production of ADH causes Diabetes insipidus." This is correct because ADH (Antidiuretic Hormone) plays a crucial role in regulating water balance in the body. When there is less ADH, the kidneys do not reabsorb enough water, leading to excessive urination and thirst, which are symptoms of Diabetes insipidus.

2. **Understanding the Reasoning (R)**: The reasoning states that "ADH helps in the reabsorption of water, producing concentrated urine in small quantities." This is also correct. ADH facilitates the reabsorption of water in the kidneys, which results in the production of concentrated urine. When ADH levels are low, the kidneys cannot reabsorb water effectively, leading to dilute urine and increased urine output.

3. **Evaluating the Relationship**: The assertion is correct, and the reasoning is also correct. Additionally, the reasoning provides a valid explanation for the assertion. Since ADH's primary function is to aid in water reabsorption, a decrease in its production directly leads to the symptoms of Diabetes insipidus.
