Four $2C-2e^-$ bonds & two $3C-2e^-$ bonds

(C) In the structure of diborane $(B_2H_6)$,there are four terminal hydrogen atoms bonded to boron atoms by normal covalent bonds,which are $2C-2e^-$ (two-center-two-electron) bonds.There are two bridging hydrogen atoms,each of which is bonded to two boron atoms by a $3C-2e^-$ (three-center-two-electron) bond,also known as a banana bond.
