Let's eliminate some answers.
Pepsi, vinegar, and orange juice all have acidic qualities. A looks like a true statement.
Bases tend to taste bitter, and since these substances are all acidic, B is not correct.
A pH above 7 is the definition of a basic substance, and, again, these are all acidic substances. C is incorrect
Litmus paper turns blue for basic substances, eliminating D
A is the correct answer

A) They are all acidic.
