The correct answer is
Distal convoluted tubule and afferent renal arteriole

JGA Components Identification

The Juxta Glomerular Apparatus (JGA) is a critical structure within the kidney responsible for regulating blood pressure and filtration rate.

This specialized region is formed by the close association of specific cellular modifications from two distinct parts related to the same nephron:

  • The Distal Convoluted Tubule (DCT): Specifically, the specialized cells called the macula densa, which are located where the DCT passes near the glomerulus.
  • The Afferent Renal Arteriole: The wall of this arteriole contains specialized smooth muscle cells known as juxtaglomerular cells.

Therefore, the JGA is formed by the distal convoluted tubule and the afferent renal arteriole.

This corresponds to Option D.
