C Correct answer
Explanation

Option (3) is grammatically the most correct option. Option (1) and (5) are incorrect because the subject (The surfacing technique) is singular and hence, will take a singular verb. (2) is incorrect because in the same sentence ‘past’ and ‘present’ tense is used. (4) is incorrect because of wrong pronoun usage (they) for a singular antecedent.
