- A–III, B–II, C–I
- A–II, B–III, C–I
- A–II, B–I, C–III
- A–I, B–II, C–III
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
- A) Electrodes in batteries → Polyacetylene (II): Polyacetylene is a conducting polymer used in electronic devices including battery electrodes.
- B) Welding of metals → Oxyacetylene (III): Oxyacetylene flame (from reaction of oxygen and acetylene) is used for metal welding due to its high temperature.
- C) Toys → Polypropylene (I): Polypropylene is a lightweight, durable plastic used in making toys.
