Answer: (B)

The prefix that signifies a "small" size in medical terminology is micro-. This prefix originates from the Greek word "mikros," which directly translates to "small" or "tiny." In a medical context, it is commonly used to denote something that is diminutive in scale. For example, terms like "microscope" refer to an instrument used to view small objects, and "microorganism" refers to organisms that are too small to be seen with the naked eye. In contrast, the other prefixes carry different meanings. Macro- means "large" or "great," used to indicate larger sizes or quantities. Intra- signifies "within" or "inside," often used in terms like "intrauterine," which refers to something occurring within the uterus. Multi- indicates "many" or "multiple," as seen in terms like "multinational." Understanding the specific definitions of these prefixes is essential for accurate communication in medical terminology.
