What is not a trigger for juxtaglomerular granular cells to release renin?

The provided question is incomplete as it lack the group of choice required to answer, however, the correct options are as follows:

A) increased extracellular fluid water levels

B) decreased filtrate NaCl concentration

C) sympathetic stimulation

D) decreased stretch due to decreased blood pressure

The correct answer is option A) increased extracellular fluid water levels

Explanation:

Juxtaglomerular granular cells are the group of cells present in the kidney that produce, store and release the enzyme known as the renin. These cells are present in the walls of the afferent arterioles mainly.

Renin is the enzyme release in order to release angiotensin I in order to increase the blood pressure. The release of the renin is depend on various triggers sense by juxtaglomerular granular cells such as decreased filtrate NaCl concentration , decreased stretch due to decreased blood pressure and sympathetic stimulation  or other stimuli. However, increased extracellular fluid water levels is not responsible for the release of renin.

Thus, the correct answer is option A) increased extracellular fluid water levels
