A is true but R is false. Nephrons are the basic filtration unit of kidneys. They carry out filtration, selective reabsorption and tubular secretion to form urine in the kidney, which is then passed out through the urethra, via the ureters and urinary bladder.

Explanation of the Assertion and Reason
The question presents two statements about the excretory unit of the kidney — the nephron. Let's analyze both the assertion (A) and the reason (R).
Assertion (A): Excretory unit of kidney is nephrons.
- This statement is true.
- Nephrons are indeed the functional units of the kidney responsible for filtering blood and forming urine.
Reason (R): It has no role in secretion of urine.
- This statement is false.
- Nephrons play a crucial role not only in filtration but also in the secretion and reabsorption processes that contribute to urine formation. They help in regulating water, electrolytes, and waste products.
Conclusion
Given that:
- Assertion (A) is true.
- Reason (R) is false.
The correct option is c) A is true but R is false. This option clearly indicates that while the assertion about nephrons being the excretory units is accurate, the reasoning provided is erroneous since nephrons are vital in the secretion of urine, contrary to what is stated in R.
Key Takeaways
- Nephrons are the fundamental units of the kidney.
- They are involved in the filtration, secretion, and reabsorption processes essential for urine formation.
- The assertion is correct, but the reason fails to accurately describe the nephron's function.
