Volatility describes how easily a substance will vaporize (turn into a gas or vapor).

\textup{Boiling point } \propto \frac{1}{\textup{Volatility}}

Water has low volatility (high boiling point) as hydrogen bonding brings association.

H2S has high volatility as no hydrogen bonding is present. Volatility decreases from H2S to H2Te

Due to increase in molecular masses of the hydrides.

Therefore, the correct option is (2).
