(C) The structure of diborane $(B_2H_6)$ consists of two boron atoms and six hydrogen atoms.There are four terminal $B-H$ bonds,which are $2$-centre-$2$-electron $(2c-2e)$ bonds.There are two bridging $B-H-B$ bonds,which are $3$-centre-$2$-electron $(3c-2e)$ bonds.Therefore,the number of $2c-2e$ bonds is $4$ and the number of $3c-2e$ bonds is $2$.

In diborane $(B_2H_6)$,the number of $2$-centre-$2$-electron bonds and $3$-centre-$2$-electron bonds respectively are:
