(B). Filtration
(C). Sedimentation
(D). Disinfection

• A. (A), (B), (C), (D)
• B. (A), (B), (C), (D)
• C. (B), (A), (C), (D)
• D. (C), (B), (D), (A)

Answer 1

The Correct Option is A

The correct sequence of steps in the water treatment process is:
Screening: The first step, used to remove large debris and particles.
Sedimentation: The process where heavier particles settle to the bottom.
Filtration: The step where finer particles are removed through a filter medium.
Disinfection: The final step to kill harmful microorganisms, usually using chlorine or UV light.
