Verified step by step guidance

1. Understand that metric prefixes are used to denote specific powers of ten, indicating multiples or submultiples of a unit.
2. Recognize that 'micro-' means one millionth (10^{-6}), which indicates a value smaller than the base unit, not greater.
3. Know that 'mega-' means one million (10^{6}), which represents a value much greater than the base unit.
4. Note that 'super-' and 'hyper-' are not standard metric prefixes but are sometimes used in general language to mean 'above' or 'excessive', though only 'mega-' is an official metric prefix indicating 'greater than'.
5. Conclude that among the given options, 'mega-' is the correct metric prefix that means 'above' or 'greater than'.
