What does the prefix 'micro-' mean?

• A. Large
• B. Small
• C. Between
• D. Many

Answer: (B)

The meaning of the prefix micro- is that it denotes something very small. It comes from Greek micros meaning small, and it’s used in words like microscope or microorganism to indicate tiny size. In many scientific contexts, micro- also marks one millionth (10^-6), but the core idea for vocabulary is simply “small.” That’s why it aligns with the option meaning small. The other meanings—large, between, or many—don’t fit with micro- because micro- does not convey those sizes or quantities.
