When vapour condenses into liquid,

Two different liquids of the same mass are kept in two identical vessels, which are placed in a freezer that extracts heat from them at the same rate, causing each liquid to transform into a solid. The schematic figure below shows the temperature $T$ versus time $t$ plot for the two materials. We denote the specific heat in the liquid states as $C_{L 1}$ and $C_{L 2}$ for materials $1$ and $2$, respectively, and the latent heats of fusion as $L_1$ and $L_2$, respectively. Choose the correct option.

The graph signifies:

Compared to a burn due to water at $100^{\circ}C$,a burn due to steam at $100^{\circ}C$ is
