B is the correct answer becoz carbonic acid is a dibasic acid and on nuetralisation is still left with a hydrogen ion while HCl being a monobasic acid is left with no hydrogen ions.

Explanation:
Acidic salts are formed when a weak acid reacts with a strong base. The resulting salt has a pH value less than 7 and is acidic in nature. However, not all acids form acidic salts. Carbonic acid is one such acid that does not form an acidic salt.
Reason:
• Carbonic acid is a weak acid that dissociates into carbon dioxide and water.
• When it reacts with a strong base, such as sodium hydroxide, the resulting salt is sodium carbonate, which is a basic salt.
• The pH value of sodium carbonate is greater than 7, making it a basic salt.
Examples of acidic salts:
• Phosphoric acid: When it reacts with a strong base, such as sodium hydroxide, the resulting salt is sodium phosphate, which is an acidic salt.
• Hydrochloric acid: When it reacts with a strong base, such as sodium hydroxide, the resulting salt is sodium chloride, which is a neutral salt.
• Sulphuric acid: When it reacts with a strong base, such as sodium hydroxide, the resulting salt is sodium sulphate, which is an acidic salt.
Conclusion:
In summary, not all acids form acidic salts. Carbonic acid is a weak acid that does not form an acidic salt. When it reacts with a strong base, the resulting salt is a basic salt. Other acids, such as phosphoric acid, hydrochloric acid, and sulphuric acid, form acidic salts when they react with a strong base.
