Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. has been working.
The original sentence contains a tense inconsistency.
Present perfect continuous tense should be used in this context to convey an ongoing action that started in the past and is still continuing.
The correct verb structure is: Have/Has + been + V-ing
"Has been working" is the correct substitution.
