Question

Match List - I shows various isotopes and List II indicates their half-lives. Match List I with List - II.

List - I	List - II
A. \(^{3}\text{H}\)	I. 60 days
B. \(^{14}\text{C}\)	II. 14.5 days
C. \(^{32}\text{P}\)	III. 5700 years
D. \(^{125}\text{I}\)	IV. 12.2 years

• A. A-I, B-III, C-IV, D-II \
• B. A-IV, B-III, C-II, D-I \
• C. A-III, B-II, C-IV, D-I \
• D. A-II, B-III, C-I, D-IV

Hint:

Carbon-14 is famous for ancient dating (thousands of years), while Phosphorus-32 decays very rapidly (around two weeks). This pairing easily unlocks the entire match question.
