Answer»

Right choice is (b) exothermic

The best explanation: One of the main important uses of diborane is that it is used in ROCKETS as a propellant. The complete COMBUSTION of diborane is highly exothermic. Though, the complete combustion in rockets isn’t possible DUE to the PRODUCTION of boron MONOXIDE.
