The answer is D because locomotive boilers are fire tube boilers, In water tube boiler the water flows through pipes the heat supplied externally so it is externally fired. La-mont the boiler is modern high-pressure boiler working pressure is 125bar.

Option C is wrong here because, "A forced circulation boiler was first introduced by La-Mont in the year 1925 which is used in Europe and America. This is a modern high pressure boiler (water tube type steam boilers) working on forced circulation system".

Internally fired means whether or not the flue gases which is the only source of heat exchange are flowing inside the tubes.

I don't understand why water tube boilers are considered as internally fired. What does internal firing refers here?
