Correct answer: B

  1. Identify each compound and its common use

    • A. Iodoform (CHI3\mathrm{CHI_3}CHI3​): used as an antiseptic.

      So, A→IIIA \to IIIA→III.

    • B. Carbon tetrachloride (CCl4\mathrm{CCl_4}CCl4​): formerly used in fire extinguishers.

      So, B→IB \to IB→I.

    • C. CFC (chlorofluorocarbon): used as refrigerants.

      So, C→IVC \to IVC→IV.

    • D. DDT: a well-known insecticide.

      So, D→IID \to IID→II.

  2. Write the complete matching

    A−III,  B−I,  C−IV,  D−IIA-III,\; B-I,\; C-IV,\; D-IIA−III,B−I,C−IV,D−II

  3. Compare with the given options

    This matches Option B.

  4. Comparison with stored correct answer

    Stored correct answer = B

    Our derived answer = B

    Hence, they agree.
