Your answer is vinegar C)
Blue litmus paper turns red in the presence of an acidic solution/compound. An acid is any substance with a pH level less than 7.
Ammonia is a moderately basic solution. It has a pH greater than 7. Therefore, it will not turn blue litmus paper red.
Baking soda is also a basic substance with a pH greater than 7. It also will not turn blue litmus paper red.
Distilled water is a neutral solution. It has a pH of 7, and it will not react with the litmus paper to change its color.
That leaves us with vinegar. Vinegar is an acid with a pH of less than 7. It will turn blue litmus paper red.
