The members of the club have been waiting eagerly for the chief guest to arrive since two hours.
Show answer & explanation
Correct answer: B
Explanation
The correct option is B because the present perfect continuous tense ('have been waiting') is used to describe an action that started in the past and is still continuing in the present. This tense requires the use of 'for' when specifying duration of time (e.g., 'for two hours,' 'for a week,' 'for a long time'). The word 'since' is used to specify a starting point in time (e.g., 'since 5 PM,' 'since Monday,' 'since 2020').
