AI Explanation

The correct answer is A) spectacle flange. A spectacle flange is a type of fitting installed in a pipeline that can either allow full flow passage through the pipe or completely block the flow by shifting a blank plate into the pipe. This allows the pipeline to be easily isolated or opened up as needed. The other answer choices do not specifically describe this type of fitting that can switch between an open and closed position to control flow.
