Select the most appropriate option to fill in the blank.
Serena _________ from fever since the 5th of this month.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. has been suffering.
The present perfect continuous tense is used to describe an action that started in the past and is continuing into the present. In this case, Serena started suffering from fever on the 5th of the month, and the fever is presumably still ongoing.
Thus, the blank is filled with "has been suffering" because this sentence refers to an action that began in the past and is still ongoing in the present.
