Which term is defined as 'Open'?

• A. Pigmentation
• B. Primary
• C. Patent
• D. Precaution

Answer: (C)

The main idea here is medical vocabulary where the word that means open or unobstructed is patent. In medical usage, patent describes passages that are open and not blocked, such as an airway that is patent, meaning air can pass through easily. You might also see patent ductus arteriosus, which refers to a duct that remains open after birth. The other terms point to different concepts: pigmentation refers to color or coloration, primary means first or main, and precaution is a safety measure taken to prevent harm. So patent is the term that directly conveys open or unobstructed.
