Answer:
Option A) Oxytocin causes the uterus to contract ,further stimulating the receptors that signal the brain to release oxytocin.!
Explanation:
Positive feedback is a mechanism in which the output of a process increases the magnitude of the process which caused that output and this loop continues.
The most common example of the Positive Feedback Mechanism is the child birth. During child birth, the child pushes on the walls of uterus. This stimulates the pressure receptors which send signals to brain to release oxytocin. This oxytocin causes the wall of uterus to contract further, which is again detected by the pressure receptors. This sends signals to the brain again and this process continues in this loop.

Explanation:
<u>Answer:</u>
In the afferent arteriole that sense blood pressure.
<u>Explanation:</u>
Background Knowledge:
Nephron: Nephron is the basic structural and functional unit of kidney. It regulates salt and water balance. Structure of nephron is divided in to two parts.
1) Renal Corpuscles: Renal Corpuscles further divided into
a) Glomerulus and
b) Bowman capsule.
Blood from Arteries enters into glomerulus through afferent arterioles and leaves through Efferent arterioles for filtration. During this process waste material become filtered from Glomerulus containing blood into the Bowam capsule.
2) Renal Tubules: Renal tubules are further divided into
a) Proximal Convulated tubules
b) Loop of Henle and
c) Distal Convulated Tubules
Waste material pass through these tubes in sequential order. Components which are needed by body become reabsorbed in to capillaries present around these tubules while rest of material pass out of the body.
Juxtaglomerular apparatus: This is specialized structure. This structure is formed by the distal convulatd tubules and glomerular afferent arteriole. Juxtaglomerular apparatus is located near the vascular pole of the glomerulus.
Function: Its main function is the regulate blood pressure and the filtration rate of the glomerulus. This structure contains specialized epithelial cells in the distal convoluted tubule. Purpose of these cells is to detect sodium concentration in the tubule. These cells trigger contraction of the afferent arteriole in case if the sodium level is present in elevated state in filtrate fluid. This whole procedure reduces glomerulus blood flow and glomerular filtration rate.
