The typical volume of urine produced from approximately 170,000 mL of filtered plasma is around 1200 mL, which is in line with known physiological values. The kidneys filter blood plasma at a rate of about 180 liters per day, and the average person typically excretes about 1 to 2 liters of urine daily.

When considering the filtration process, around 99% of the filtered plasma is reabsorbed back into the bloodstream. This means that from the 170,000 mL of filtered plasma, a substantial portion is reabsorbed. Therefore, calculating based on typical reabsorption rates leads to an expected urine output of around 1200 mL, representing a balance between waste elimination and maintaining body fluid homeostasis.

Values significantly higher or lower than this, such as those indicated by the other options, would generally not reflect normal physiological processes. For instance, 600 mL might suggest a form of oliguria, which is not typical under normal conditions, while 2000 mL or 3000 mL would be indicative of polyuria, often associated with specific medical conditions.
