Correct order of bond angle is :-

5.1g NH₄SH is introduced in 3.0 L evacuated flask at 327°C. 30% of the solid NH₄SH decomposed to NH₃ and H₂S as gases. The K_p of the reaction at 327°C is (R = 0.082 L atm mol^-1K^-1,
Molar mass of S = 32 g mol^-1,
Molar mass of N = 14g mol^-1)

Statement I: The bond dissociation energy of a molecule is higher for a sigma bond than for a pi bond.

Statement II: Sigma bonds have greater orbital overlap compared to pi bonds, making them stronger.
