Solution
The correct option is A 1, 3 and 4 are correct
Boron has 4 hybridised orbitals, out of which 3 orbitals are occupied with one electron each and rest one is an empty orbital.
B−H−B bond angle is less than 180∘
There are two terminal B-H bonds for each boron atom.
There are only 12 valence electrons, 3 in each B atom and 1 in each H atom. Thus there are only 12 bonding electrons available.
