Answer

c
Elements with highest electronegativity $\rightarrow \mathrm{F}, \mathrm{O}$

Elements with largest atomic size $\rightarrow \mathrm{Fr}, \mathrm{Ra}$

Elements which shows properties of both metal and non-metals i.e. metalloids $\rightarrow \mathrm{Ge}$, As

Elements with highest negative electron gain enthalpy $\rightarrow \mathrm{Cl}, \mathrm{S}$
