What is the abbreviation and value of the prefix micro?

Explanation:
Micro represents one-millionth, written with the symbol μ (the Greek mu). In plain text you might see 'u', but the official SI symbol is μ. The value is 10^-6, which equals 0.000001. So the correct pairing is μ with 0.000001. The other options either use the nonstandard symbol 'u' or pair μ with a different power of ten (like 0.00001 for 10^-5 or 0.0000001 for 10^-7), which do not match micro.
