Answer:
E. juxtaglomerular complex
Explanation:
Macula densa cells are the columnar tubule cells. They are present in the wall of afferent arterioles. The modified fibers of smooth muscles present in the lining of the afferent arteriole are called juxtaglomerular cells.
The juxtaglomerular cells and macula densa cells together make the juxtaglomerular apparatus, also called juxtaglomerular complex. The function of the juxtaglomerular apparatus is to maintain the blood pressure of kidneys.
