Best 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.
