Rationale: The correct answer is D: 1,000 mg. This is because 1 gram is equivalent to 1,000 milligrams. To convert grams to milligrams, you multiply by 1,000. Choices A, B, and C are incorrect. Choice A (1 mg) is the smallest unit, and it would take 1,000 of these to make 1 gram. Choice B (10 mg) is also too small, as it would require 100 of these to equal 1 gram. Choice C (100 mg) is closer, but it still falls short of the correct conversion, which is 1,000 mg in 1 gram.

Choice A (60 ml) is incorrect because it represents 0.06 liters. Choice C (6 ml) is incorrect as it would be the milliliter equivalent for 0.006 liters. Choice D (6000 ml) is incorrect as it would be the milliliter equivalent for 6 liters.
