{'indigestion': [1, 0, 0, 1], 'much hydrochloric acid': [0, 0, 0, 1], 'acid present': [0, 0, 0, 1], 'major reactant': [0, 0, 0, 1], 'mgco3': [0, 0, 0, 1], 'tablet': [0, 1, 0, 1], 'stomach': [0, 0, 1, 1], 'reacts': [1, 0, 0, 1]}

The correct answer is option 3, NaOH. The reason this would be inappropriate to include as a major reactant in the tablet is because sodium hydroxide (NaOH) is a strong base and can cause further irritation and damage to the stomach lining. It is not suitable for treating indigestion caused by excess stomach acid.

Option 1, CaCO3 (calcium carbonate), and option 2, MgCO3 (magnesium carbonate), are both appropriate reactants to include in the tablet. They are commonly used as antacids because they can neutralize excess stomach acid and provide relief from indigestion.

Option 4, Mg(OH)2 (magnesium hydroxide), is also an appropriate reactant to include. Magnesium hydroxide can react with hydrochloric acid to form magnesium chloride and water, effectively reducing the amount of acid in the stomach and providing relief.

In summary, while options 1, 2, and 4 would be suitable reactants to include in the tablet, option 3, NaOH, would be inappropriate due to its strong basic nature.
