Answer:
The preferable option will be - B.
B. juxtaglomerular complex.
Explanation:
The cells of the macula densa, the juxtaglomerular cells, and the extraglomerular mesangial cells together form <u>the juxtaglomerular complex or juxtaglomerular apparatus.
</u>
The given options were -
a. nephron loop (loop of Henle).
b. juxtaglomerular complex.
c. renal corpuscle.
d. filtration membrane.
e. afferent arteriole.
- The juxtaglomerular apparatus regulates the blood pressure and also regulates the filtration rate of the glomerulus.
C can be taken out of the question as eukaryotic cells do not have a nucleus. A lysosome is is only in prokaryotic cells so B can be taken out of the question. The answer should be D.
