Select the option that will improve the highlighted part of the given sentence.
You are so efficient as he.

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.
Information Booster:
· "So...as" is typically used in negative comparisons.
· ✔ Correct: He is not so tall as his brother.
· ❌ Incorrect: He is so tall as his brother (in affirmative).
