Given below are two statements: One is labelled as Assertion (A) and the other is labelled as Reason (R).
In the light of the above statements, choose the correct answer from the options given below:
| Assertion (A): | Juxta Glomerular Apparatus (JGA) plays an important role in regulation of glomerular filtration rate (GFR). |
| Reason (R): | A fall in GFR can activate the J.G. cells to release renin which can stimulate the glomerular blood flow and thereby bringing the GFR to normal level. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
| 3. | (A) is True but (R) is False. |
