The answer is the fourth one (d): Capillaries, glomerular capsule, proximal convoluted tubule, nephron loop, distal convoluted tubule, collecting duct, ureter.
Explanation for each option:
a. Ureter, collecting duct, capillaries, proximal convoluted tubule, distal convoluted tubule, nephron loop, glomerular capsule - Incorrect. This sequence is not in the correct order of the nephron's filtration process. The ureter is not part of the nephron; it is involved later in the transport of urine.
b. Glomerular capsule, distal convoluted tubule, nephron loop, proximal convoluted tubule, capillaries, collecting duct, ureter - Incorrect. The order of the tubules is incorrect. The proximal convoluted tubule comes before the nephron loop, and the capillaries are not part of the direct path of filtrate through the nephron.
c. Ureter, capillaries, distal convoluted tubule, proximal convoluted tubule, glomerular capsule, nephron loop, collecting duct - Incorrect. The ureter and capillaries are misplaced in the sequence, and the order of the tubules is incorrect.
d. Capillaries, glomerular capsule, proximal convoluted tubule, nephron loop, distal convoluted tubule, collecting duct, ureter - Correct. This sequence accurately describes the path of filtrate through the nephron: blood is filtered from the capillaries into the glomerular capsule, then it passes through the proximal convoluted tubule, nephron loop, distal convoluted tubule, and collecting duct before being transported to the ureter.
In summary, option d correctly outlines the path through which plasma is filtered into urine through the nephron.
