Question

Match List-I with List-II:
\begin{tabular{ll} List-I (Polymeric material for Packaging) & List-II (Relative ratio of permeability of CO\(_2\) to O\(_2\))
(A) Low-density Polyethylene & (I) 6.4
(B) Silicon rubber & (II) 2.9
(C) Cast Polypropylene & (III) 4.6
(D) High-density Polyethylene & (IV) 3.3

Choose the correct answer from the options given below:

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

Hint:

Silicon rubber is famous for having the highest gas permeability and the highest $P_{\text{CO}_2} / P_{\text{O}_2}$ ratio (6.4) among common polymeric packaging materials.
Matching (B) with (I) immediately identifies the correct option.

Answer 1

The Correct Option is D
