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:

  1. i – a, ii – c, iii – d, iv – b
  2. i – b, ii – c, iii – a, iv – d
  3. i – d, ii – a, iii – c, iv – b
  4. i – c, ii – d, iii – b, iv – a

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.
