Consider the following statements regarding the chemistry of antacids: 1. Excessive use of soluble hydrogen carbonates (like sodium bicarbonate) can make the stomach alkaline and trigger the production of even more acid. 2. Metal hydroxides (like magnesium and aluminum hydroxides) are preferred over sodium bicarbonate because they are insoluble and do not increase the pH of the stomach above neutrality. 3. Cimetidine and Ranitidine work by neutralizing the acid already present in the stomach. Which of the statements given above is/are correct?

Options:

• A: 2 and 3 only
• B: 1 and 3 only
• C: 1 and 2 only
• D: 1, 2 and 3
