Identify the reaction/process in which the entropy increases.

$$\mathrm{H}(\mathrm{g})+\mathrm{H}(g) \longrightarrow \mathrm{H}_2(g)$$

$$\mathrm{H}_2 \mathrm{O}(\mathrm{g}) \longrightarrow \mathrm{H}_2 \mathrm{O}(\mathrm{s})$$

$$\mathrm{H}_2 \mathrm{O}(\mathrm{l}) \longrightarrow \mathrm{H}_2 \mathrm{O}(\mathrm{g})$$

$$A(g)+B(g)+C(s) \longrightarrow 2 D(s)$$
