(B) Materials with high conductivity (typically $> 10^2 \ S \ m^{-1}$) are classified as conductors.Given values in $S \ m^{-1}$ are: $2.1 	imes 10^3$,$1.0 	imes 10^{-16}$,$1.2 	imes 10$,$3.91$,$1.5 	imes 10^{-2}$,$1 	imes 10^{-1}$,$1.0 	imes 10^3$.$1$. $2.1 	imes 10^3$ (Conductor)$2$. $1.0 	imes 10^{-16}$ (Insulator)$3$. $1.2 	imes 10$ (Semiconductor)$4$. $3.91$ (Semiconductor)$5$. $1.5 	imes 10^{-2}$ (Semiconductor)$6$. $1 	imes 10^{-1}$ (Semiconductor)$7$. $1.0 	imes 10^3$ (Conductor)There are $2$ materials with high conductivity values ($2.1 	imes 10^3$ and $1.0 	imes 10^3$).Therefore,the number of conductors is $2$.

The values of conductivity of some materials at $298.15 \ K$ in $S \ m^{-1}$ are $2.1 \times 10^3$,$1.0 \times 10^{-16}$,$1.2 \times 10$,$3.91$,$1.5 \times 10^{-2}$,$1 \times 10^{-1}$,$1.0 \times 10^3$. The number of conductors among the materials is............
