B)is an effective, inexpensive, disinfectant able to destroy all types of microorganisms.
C)is unaffected by the presence of organic material.
D)is ineffective when diluted.
E)readily reacts with organics to produce potentially carcinogenic trihalomethanes AND is an effective, inexpensive, disinfectant able to destroy all types of microorganisms.

Accepted Answer

Chlorine can react with organic materials to produce potentially carcinogenic trihalomethanes, but it is still a highly effective and inexpensive disinfectant capable of destroying all types of microorganisms. Therefore, both A and B are correct statements. Chlorine is able to disinfect even in the presence of organic material, so C is incorrect. Chlorine can still be effective when diluted, so D is also incorrect.
