• D. mega — 10^6

Answer: (D)

Verified step by step guidance

1. Recall that metric prefixes represent specific powers of ten, which serve as multipliers to the base unit.
2. Identify the correct multiplier for 'kilo': it corresponds to \$10^{3}$, meaning 1 kilo-unit equals 1000 units.
3. Check the prefix 'centi': it actually means \$10^{-2}\(, not \)10^{2}$, so 1 centi-unit equals 0.01 units.
4. Examine 'micro': it corresponds to \$10^{-6}\(, not \)10^{-3}$, so 1 micro-unit equals 0.000001 units.
5. Confirm 'mega': it correctly corresponds to \$10^{6}$, meaning 1 mega-unit equals 1,000,000 units.
