(C) In the structure of diborane $(B_2H_6)$,there are two types of hydrogen atoms: terminal and bridging.$1$. The terminal $B-H$ bonds are $2$-center-$2$-electron $(2C-2e)$ bonds.$2$. The bridging $B-H-B$ bonds are $3$-center-$2$-electron $(3C-2e)$ bonds.$3$. The angle $	heta_1$ represents the $H-B-H$ bond angle between the two bridging hydrogen atoms,which is approximately $97^{\circ}$.$4$. The angle $	heta_2$ represents the $H-B-H$ bond angle between the two terminal hydrogen atoms,which is approximately $120^{\circ}$.Therefore,$	heta_1 = 97^{\circ}$ and $	heta_2 = 120^{\circ}$.

In the given structure of Diborane,$\theta_1$ and $\theta_2$ are respectively:
