Diborane is simplest and most familiar hydride of boton. Its chemical formula is `B_(2)H_(6)`. Comparing with ethane, diborane is regarded as electron deficient molecule. In the excited state boron of diborane undergoes `sp^(3)` hybridisation. Bonding in doborane is described as tricentric two electron bonding.

A. 1
B. 2
C. 3
D. 4
