An infusion prepared with 25,000 units of heparin in 500 ml of saline solution yields 50 units of heparin per milliliter of solution. The equation is set up as 50 units times X (the unknown quantity) equals 1,500 units/hour, X equals 30 ml/hour.

Option A: 15 ml/hr is incorrect based on the computation used.

Option C: 45 ml/hr is more than the correct milliliters to be infused based on the computation.

Option D: 50 ml/hr is incorrect because it is way more than the correct milliliter to be infused.
