Which method of water purification does not kill microorganism?
Answer: B
Filtration does not kill micro-organisms. It removes suspended matter and, with a fine enough filter, most bacteria and protozoan cysts, but whatever passes through is still alive.
Boiling, chlorination and ultraviolet irradiation all destroy the organisms rather than merely removing them.
