Which prefix denotes 10^3 (1000)?

Explanation:
Powers of ten are represented by SI prefixes; each prefix scales a unit by a fixed factor. For a thousand, the prefix is kilo-, so one kilometer is 1000 meters. The other options correspond to different powers: 10^6 is mega-, making a unit a million times larger; 10^-3 and 10^-2 are milli- and centi-, which create thousandths and hundredths, respectively. Therefore, the prefix that denotes 10^3 (1000) is kilo-.
