The prefix con means which?

• A. Colon
• B. With, Together
• C. Gelatin, Neck
• D. Against, Opposed

Answer: (B)

Con- is a Latin prefix meaning with or together. It shows that things are being brought together or joined. That’s why it fits phrases like contact (touching together), connective tissue (tissues that connect), congenital (present with birth), and concentrate (to bring parts together into a denser form). So the option that corresponds to meaning "With, Together" is the best choice. The other options refer to different ideas (colon, gelatin/neck, or against/opposed) and don’t reflect this prefix.
