What is vaporization? What is normal boiling point?

The graph signifies:

Match the following items in Column-$I$ with their corresponding definitions in Column-$II$.

Column-$I$	Column-$II$
$A$. Conversion of liquid into solid is	$1$. Regelation
$B$. Conversion of liquid into vapour is	$2$. Sublimation
$C$. Conversion of solid into vapour directly is	$3$. Fusion
$D$. Melting of ice caused by pressure is	$4$. Vaporisation

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.

$A$ solid material is supplied with heat at a constant rate. The temperature of the material changes with heat input as shown in the figure. What does the slope of $DE$ represent?

Values for latent heat in Column-$I$ and its values are given in Column-$II$. Match the following:

Column-$I$	Column-$II$
$(a)$ Latent heat of vaporization $L_V$	$(i)$ $22.6 \times 10^5 \, J/kg$
$(b)$ Latent heat of fusion $L_f$	$(ii)$ $33.3 \times 10^5 \, J/kg$
	$(iii)$ $3.33 \times 10^5 \, J/kg$
