Matching Water Treatment Purposes

Steps:

• Sedimentation settles out heavy particles, and filtration traps smaller solids to clarify water.
• Chlorine treatment acts as a disinfectant to kill harmful microbes like bacteria.
• Activated carbon adsorption removes organic compounds causing tastes and odors.
• Compare choices to standard processes: solids removal first, then disinfection, then taste improvement.

Why B is correct:

• Sedimentation and filtration remove suspended solids via physical separation; chlorine kills microbes through oxidation, as per standard water purification definitions.

Why the others are wrong:

• A: Reverses solids removal and microbe killing, ignoring physical vs. chemical roles.
• C: Assigns taste removal to chlorine (disinfectant) and microbe killing to carbon (adsorbent).
• D: Misplaces solids removal to carbon and tastes to initial filtration steps.

Final answer: B
