Match List-I with List-II:
| List-I | List-II | ||
|---|---|---|---|
| i | Li | a | Absorbent for carbon dioxide |
| ii | Na | b | Electrochemical cells |
| iii | KOH | c | Coolant in fast breeder reactors |
| iv | Cs | d | Photoelectric cell |
Choose the CORRECT answer from the options given below:
Correct answer · Option 2
i – b, ii – c, iii – a, iv – d
Explanation
Li is used in electrochemical cells (i-b), Na liquid alloy is used as coolant in fast breeder reactors (ii-c), KOH is used as an absorbent for carbon dioxide (iii-a), and Cs is used in photoelectric cells due to low ionization energy (iv-d). Matching gives i-b, ii-c, iii-a, iv-d.
