Answer 1

A is wrong becasue it didn't have to put a comma in these areas >> paper, and,

B is wrong because "and," the comma should be before "and".

c. The deacidification process preserves pages by neutralizing acid with magnesium oxide, raising the pH level of the paper, and minimizing the alkaline reserve. << THIS IS CORRECT


D is wrong becasue "paper and minimizing" there should have been a comma before "and"

Hope this helps.
