The Correct Option is A

Solution and Explanation

Step 1: Understanding renin secretion.
Renin is a hormone-enzyme involved in the regulation of blood pressure, blood volume, and sodium balance in the body.

Renin is secreted by the juxtaglomerular (JG) cells present in the walls of the afferent arteriole of the nephron. These cells collectively form the JG apparatus.
