Show answer & explanation
Correct answer: A
Explanation
Correct Answer
The proposed legislation has been being challenged for its lack of clarity and enforcement mechanisms by industry leaders.
Explanation
The original sentence is in the Present Perfect Continuous tense (have been challenging). To change it into passive voice:
The object (the proposed legislation) becomes the new subject.
The active verb structure "has/have + been + V1 + ing" converts into the passive structure "has/have + been + being + V3".
Because "the proposed legislation" is singular, we use has been being challenged.
While the present perfect continuous passive structure is rare and sounds clumsy in everyday speech, it is grammatically correct and necessary to maintain the exact tense of the original sentence.
Key Points
Active: Subject + have/has + been + V1 + ing + Object
Passive: Object + has/have + been + being + V3 + by Subject
Rule: Do not change the tense (e.g., converting it to was challenged or is being challenged changes the time frame of the action).
