(A) The structure of $B_2H_6$ (diborane) consists of two $BH_2$ groups in the same plane.There are $4$ terminal $B-H$ bonds,which are $2$-centered-$2$-electron $(2c-2e)$ bonds.There are $2$ bridge $B-H-B$ bonds,which are $3$-centered-$2$-electron $(3c-2e)$ bonds.There is no direct $B-B$ bond in $B_2H_6$.Thus,the number of $BH_2$ groups in one plane is $2$,terminal $B-H$ bonds is $4$,$B-B$ bonds is $0$,and $B-H-B$ bridge bonds is $2$.

In the structure of $B_2H_6$,the number of $BH_2$ groups present in one plane,and the number of $B-H$ terminal bonds,$B-B$ bonds,and $B-H-B$ bridge bonds are respectively:
