Match List-I with List-II

Choose the correct answer from the options given below:

(A)-(I), (B)-(III), (C)-(IV), (D)-(II)

The correct answer is Option (3) → (A)-(I), (B)-(III), (C)-(IV), (D)-(II)

(A) Gold: As a metal, gold is an excellent conductor. Its conductivity is very high, typically in the range of $10^3$ to $10^7 \text{ S m}^{-1}$. From the options, the highest value is $4.5 \times 10^3 \text{ S m}^{-1}$.

(B) Glass: Glass is a well-known insulator. Insulators have extremely low conductivity values. The value $1.0 \times 10^{-16} \text{ S m}^{-1}$ represents the typical range for an insulator like glass.

(C) Silicon: Silicon is a semiconductor. Its conductivity lies between that of conductors and insulators. Pure (intrinsic) silicon has a moderate conductivity value, which matches $1.5 \times 10^{-2} \text{ S m}^{-1}$.

(D) Pure water: Pure water is a very poor conductor (a weak electrolyte) due to the low concentration of $H^+$ and $OH^-$ ions. Its conductivity is approximately $3.5 \times 10^{-5} \text{ S m}^{-1}$ (or $3.5 \times 10^{-3}$ depending on the source units; in this list, it corresponds to (II)).
