Choice A incorrectly moves the decimal point, choice C multiplies instead of divides, and choice D adds an extra zero.

Correct Answer: A

Rationale: The correct answer is A: 500 ml. To convert liters to milliliters, you multiply by 1000 because there are 1000 milliliters in 1 liter. So, 0.5 liter x 1000 = 500 ml.
