Final answer:
One of the three general processes involved in urine formation is secretion. The other two processes are glomerular filtration and tubular reabsorption.
Step-by-step explanation:
The correct answer to the question "Which of the following is one of the three general processes involved in formation of urine?" is B. Secretion. The three steps in the formation of urine are glomerular filtration, which occurs in the glomerulus; tubular reabsorption, which occurs in the renal tubules; and tubular secretion, also in the renal tubules. Tubular secretion is the process where wastes that do not get reabsorbed are actively secreted into the renal tubules to be excreted in urine. This is part of how the kidneys maintain the body's chemical balance.
