Which prefix represents 0.001?

Explanation:
This question tests understanding of metric prefixes that denote powers of ten. 0.001 is 10^-3, which corresponds to a thousandth. The prefix that means a thousandth is milli, so one milli-unit is 0.001 of the base unit (for example, 1 millimeter is 0.001 meters). In contrast, kilo means 10^3, mega means 10^6, and giga means 10^9, which are much larger than 0.001. So the correct prefix is milli.
