Options

  1. APb CH 3 COO 2
  2. BAl CN 3
  3. CCH 3 COOK
  4. DFeCl 3

Correct answer

C. CH 3 COOK

Step-by-step solution

Salt of Pb ( OH ) 2 +   CH 3 COOH Weak base Weak acid Salt of     Al ( OH ) 3 + HCN Weak base Weak acid Salt of Fe ( OH ) 3 + HCl Weak base Strong acid Hence, the nature of the solution is basic.
