Select the most appropriate option that can substitute the highlighted segment in the given sentence.
Mahira is an more efficient and hardworking employee of her company.

Correct option is B

The correct substitution of the highlighted words is "Mahira is an efficient".
· The article "an" is used before words that begin with a vowel sound. However, "more" does not need an article before it.
· The correct sentence should be: "Mahira is an efficient and hardworking employee of her company."
· Grammatical Rule Used: "An" is used before words that begin with a vowel sound (e.g., "an apple," "an honest man").
· "More" is used for comparisons, and it should be accompanied by "the" if comparing two things.
Example:
❌ Incorrect: She is an more talented dancer than him.
