Match List I with List II.

List-I (Elements)	List-II(Properties in their respective groups)
A	$\text{Cl},\text{S}$	I.	Elements with highest electronegativity
B.	$\text{Ge},\text{As}$	II.	Elements with largest atomic size
C.	$\text{Fr},\text{Ra}$	III.	Elements which show properties of both metals and non-metal
D.	$\mathrm{F, O}$	IV.	Elements with highest negative electron gain enthalpy

Choose the correct answer from the options given below

$\mathrm{Cl}$ and $\mathrm{S}$ have highest negative electron gain enthalpy in their groups. Hence, A-IV.

$\mathrm{Ge}$ and $\mathrm{As}$ are metalloids and show both metallic and non-metallic properties. Hence, B-III.

$\mathrm{Fr}$ and $\mathrm{Ra}$ are bottom elements of their groups and have largest atomic size. Hence, C-II.

$\mathrm{F}$ and $\mathrm{O}$ have highest electronegativity in their respective groups. Hence, D-I.

Therefore, the correct option is C.
