List I (Element):
- AIsotope of Uranium,
- BIsotope of Cobalt,
- CIsotope of Iodine,
- DIsotope of Radium
List II (Application):
- 1Treatment of cancer,
- 2Treatment of goitre,
- 3Treatment of secondary cancer,
- 4Nuclear fuel
Code: A B C D
general-sciencechemistry
- A3 2 1 4
- B4 2 1 3
- C4 1 2 3
- D3 1 2 4
Explanation
The correct applications are: the uranium isotope as nuclear fuel (4), the cobalt isotope (cobalt-60) in cancer treatment (1), the iodine isotope (iodine-131) in treating goitre (2), and the radium isotope in treating secondary cancers such as bone metastases (3). This gives the code 4 1 2 3.
