Concept:The sentence becomes grammatically correct and meaningful when the actions “passed” and “highlighted” are swapped between the Chief Justice and the legislature.
Explanation:The original sentence is incorrect because the Chief Justice cannot “pass” a Bill, and a legislature cannot “highlight” a Bill.
After interchanging A and C, the sentence becomes:
“The Chief Justice highlighted that sitting on competent Bills passed by a legislature undermines democracy.”
Here, “highlighted” correctly describes the Chief Justice’s action.
“Passed” correctly describes the legislature’s action of approving the Bills.
Therefore, only the pair A-C needs to be interchanged.
Answer:Option 1: A-C
