The symbol for micro- prefix is which of the following?

Explanation:
The concept being tested is how the micro- prefix is represented. Micro- denotes one millionth of a unit, which is 10^-6. The symbol used to indicate this prefix is the Greek letter mu, written as μ. This distinguishes micro- from the other SI prefixes: milli is m (10^-3), nano is n (10^-9), and pico is p (10^-12). So you’d write something like microgram (μg) or microsecond (μs) to show one millionth of those units.
