Correct answer is (a) M type

Easiest explanation: M typeis used as rear header in a U-Tube heat exchanger. The U-tubes permit unlimited thermal extension, the bundles of the tubes can be removed to clean. But internal cleaning of the tubes are difficult due to the small diameter, therefore the fluids are filtered before entering into the feed pipe.
