Correct Answer: C
Solution :
Producer gas is a mixer of flammable gases (CO and \[{{H}_{2}}\]) and non-flammable gases (\[{{N}_{3}}\] and\[C{{O}_{2}}\]). In a nuclear reactor, the moderator is either heavy water or graphite etc. Lubricating oil has boiling range from \[300{}^\circ C\] to \[370{}^\circ C.\]
