Which of the following is not a correct statement?

What is the $H-S-H$ bond angle in $H_2S$ (in $^{\circ}$)?

$BCl_3$ is a planar molecule while $NCl_3$ is pyramidal,because

$S +$ Conc. $H_2SO_4 \longrightarrow X + Y$
Here $X$ is a gas and $Y$ is a liquid and both are triatomic molecules. The number of electron lone pairs present on the central atoms of $X$ and $Y$ are respectively.

What is the molecular geometry of $H_3O^{+}$?
