Match List - I with List - II.

List I (Compound)	List II (Use)
(A) Carbon tetrachloride	(I) Paint remover
(B) Methylene chloride	(II) Refrigerators and air conditioners
(C) DDT	(III) Fire extinguisher
(D) Freons	(IV) Non Biodegradable insecticide

Choose the correct answer from the options given below :

<p>Each of the compounds listed in List I has distinct uses. Let's match them correctly with the uses mentioned in List II:</p> <ul> <li><strong>Carbon tetrachloride (A)</strong> was historically used as a cleaning agent, among other things, but due to its toxicity and role in ozone depletion, it is no longer widely used for this purpose; hence it does not match with any of the uses. However, it was previously used in fire extinguishers, so one might think of it in association with (III).</li> <br/><li><strong>Methylene chloride (B)</strong>, also known as dichloromethane, is commonly used as a solvent and paint remover, so it matches with (I).</li> <br/><li><strong>DDT (C)</strong> is a well-known, though now largely banned, insecticide due to its persistence and bioaccumulation, making it not biodegradable. It matches with (IV).</li> <br/><li><strong>Freons (D)</strong> is a trade name for a group of halogenated compounds used primarily as refrigerants, so it matches with (II).</li> </ul> <p>Considering these associations, we can match the compounds with their correct uses:</p> <ul> <li>(A) Carbon tetrachloride - (III) Fire extinguisher</li> <li>(B) Methylene chloride - (I) Paint remover</li> <li>(C) DDT - (IV) Non-biodegradable insecticide</li> <li>(D) Freons - (II) Refrigerators and air conditioners</li> </ul> <p>So, the correct match according to the given options will be:</p> <p>Option B: <br/> (A)-(III), (B)-(I), (C)-(IV), (D)-(II)</p>
