Match List I with List II :

List-I
Elements		 List-II
Properties
(a) Li (i) Poor water solubility of I−{I^ - } salt
(b) Na (ii) Most abundant element in cell fluid
(c) K (iii) Bicarbonate salt used in fire extinguisher
(d) Cs (iv) Carbonate salt decomposes easily on heating


Choose the correct answer from the options given below :

Multiple Choice Options

  • A (a)-(iv), (b)-(iii), (c)-(ii), (d)-(i)
  • B (a)-(i), (b)-(iii), (c)-(ii), (d)-(iv)
