D
None of these.

Answer
Correct option: C.
Both $(A)$ and $(b)$
In the structure of diborane, each $B$ atom uses $sp^3$-hybridised orbital for bonding. Out of the four $sp^3 -$hybridised orbitals on each $B$ atom, one is without an electron shown by dotted lines. The terminal $B-H$ bonds are normal $2$ centre$-2$ electron bonds but the two bridge bonds are $3$ centre$-2$ electron bonds. The $3$ centre$-2$ electron bridge bonds are also refered as banana bonds.
