The correct option is C A and
D
Solution: Correct Answer Option: (c) Statement (A) is grammatically correct. Statement (D) does not have any mistake either. Statement (C) is incorrect because of the wrong usage of the adjective 'offending' with chemicals. Moreover, when "an" is used, "chemical" and not "chemicals" should be used.
In Statement (B) "making them to break apart" is wrong usage
Thus answer option (c) is the right answer choice.
