Select the most appropriate option that can substitute the underlined segment in the given sentence.
I was waiting from two hours.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. for.
The underlined part of the sentence is grammatically incorrect.
To correctly express the duration of time for which the speaker was waiting, the preposition "for" should be used instead of "from."
The use of "for" correctly conveys the idea that the speaker was waiting over the course of two hours.
The correct sentence is: I was waiting for two hours.
