PLZ GUYS

Q21 The functional groups that react with Na are CO2H and OH, so three of any of these should be present in the compound. B and D are ruled out. NaOH will react with CO2H, so there should be 1 CO2H and 2 OH groups.
Q23

As the compounds reacts with itself to form the compound shown it must have both -OH and -COOH groups.
if we break up the compound we get one single product.
