Choice B (250 mcg) is incorrect as it incorrectly multiplies by 10 instead of 1000. Choice C (2.5 mcg) is incorrect as it drops a zero from the conversion. Choice D (0.25 mcg) is incorrect as it adds an extra zero to the answer.

Choice C (3/4) is incorrect as it is not equivalent to 0.875. Choice D (9/10) is incorrect as it does not match the decimal value of 0.875.

Rationale: To convert 0.20 liters to milliliters, we know that 1 liter is equal to 1000 milliliters. Therefore, 0.20 liters = 0.20 x 1000 = 200 milliliters. So, the correct answer is A: 200 ml. Choice B (20 ml) is incorrect as it represents 0.02 liters. Choice C (2 ml) is incorrect as it represents 0.002 liters. Choice D (2000 ml) is incorrect as it is the result of incorrectly multiplying 0.20 liters by 1000 twice.
