Parts of the following sentence are given as options. Identify the segment that contains a grammatical error.
Ramprasad has not been able to come to work since a week due to fever.

Correct option is D

The segment of the sentence that contains a grammatical error is option (d) since a week
· The phrase "since a week" is incorrect. "Since" is used to indicate the starting point of an action or event that continues up to the present. It should be followed by a specific point in time (e.g., a date, a day, or a specific event), not a duration. The correct preposition for duration is "for."
· Correct Phrase: "for a week" should be used to indicate the duration of time.
· Corrected Sentence:
· "Ramprasad has not been able to come to work for a week due to fever."
Grammatical Rule Involved:
· Use of Prepositions with Time:
· "Since": Used to refer to a specific point in time when something began (e.g., since Monday, since last week, since 2010).
· "For": Used to indicate the duration of an action or state (e.g., for a week, for three hours, for ten years).
Example for Clarity:
· Correct: "I have been studying for two hours."
· Correct: "I have been studying since 3 PM."
· Incorrect: "I have been studying since two hours."
