Which of the following statements is correct regarding the regulation of kidney function?

Which of the following are related to the control of human kidney functions?
$A.$ Osmoreceptors in the body get activated by excess loss of fluid,which results in the inhibition of $\text{ADH}$ secretion.
$B.$ $A$ fall in $\text{GFR}$ can activate the release of renin.
$C.$ Low blood flow to the atria stimulates the secretion of $\text{ANF}$.
$D.$ $\text{ANF}$ acts as a check on the renin-angiotensin mechanism.
$E.$ $\text{ADH}$ can also affect kidney function by its constrictory effect on blood vessels.
Choose the correct answer from the options given below:

Choose the correct option for $A, B, C$ from the given options based on the provided flowchart of the Renin-Angiotensin-Aldosterone System $(RAAS)$.

Arrange the following events occurring in the Renin-Angiotensin mechanism in the correct order:
$A$. Increase in blood pressure and Glomerular filtration rate.
$B$. Reabsorption of $Na^+$ and water from distal parts of the tubule due to Aldosterone.
$C$. Fall in Glomerular filtration rate.
$D$. Vasoconstriction by Angiotensin $II$ and release of Aldosterone.
$E$. Renin converts Angiotensinogen into Angiotensin $I$, followed by Angiotensin $II$.

Erythropoietin hormone which stimulates $R.B.C.$ formation is produced by :

In cases of excessive bleeding,profuse sweating,or prolonged delay in fluid intake,what happens to the glomerular filtration rate?
