Permanent Pool Group is described as which of the following?

• A. Bodies of quiet, fresh water exposed to sunlight and abundant vegetation and flotage at the air-water-plant interface
• B. Rivers with fast current
• C. Brackish marshlands
• D. Ephemeral rain pools

Answer: (A)

Permanent pools refer to quiet, fresh-water bodies that are exposed to sunlight and have abundant vegetation plus material floating at the air-water interface. This combination creates a stable, sunlit habitat with plant matter and surface debris that mosquitoes can utilize for larval development and shelter. The other options don’t fit because a fast-moving river isn’t a still pool, brackish marshlands have salinity, and ephemeral rain pools are temporary and may dry up rather than persisting.
