Best answer
The correct option is (a) Single deck system

Explanation: In a single deck system spray nozzles are arranged at the same elevation. Its effective cooling effect is less than double deck system. Hot water is sprayed through the spray nozzle in air. Cooling occurs due to the evaporation of water vapors at the spray propels and falls down the surface.
