If both assertion and reason are true and reason is the correct explanation of assertion

if both assertion and reason are true but reason is not the correct explanation of assertion.

if assertion is true but reason is false

if both assertion and reason are false.

Glomerular filtration rate (GFR) is :

amount of filtrate reabsorbed at the collecting ducts

amount of filtrate formed in both kidneys each minute

rate of bladder filling

amount of blood delivered to the kidney each minute

A fall in glomerular filtration rate (GFR) activates

juxtaglomerular cells to release renin

adrenal cortex to release aldosterone

adrenal medulla to release adrenaline

posterior pituitary to release vasopressin.
