Correct option is A
The correct substitution of the highlighted part is (a)
as efficient as him.
Explanation:
· The sentence intends to
compare the efficiency of “you” with “him.”
· The correct structure for expressing
equality in comparison is:
·
as + adjective + as + object pronoun
· Hence,
"as efficient as him" is the correct and grammatically sound construction.
Grammatical Rule Used:
· For comparisons of
equality, the structure is:
·
as + adjective/adverb + as + noun/pronoun (objective case)
· Use the
objective case of the pronoun (e.g., him, her, me, us) after “as” when it functions as the object.
Example:
· Incorrect: She is so intelligent as he.
· Correct: She is
as intelligent as him.
