Reactants and Observations:
- The reactants in the flask are magnesium carbonate and hydrochloric acid.
- When these two substances react, bubbles of gas are produced.
- The gas turns lime water into milky, indicating the presence of carbon dioxide.

Explanation:
- Magnesium carbonate (MgCO3) reacts with hydrochloric acid (HCl) to form magnesium chloride (MgCl2), water (H2O), and carbon dioxide (CO2) gas.
- The carbon dioxide gas produced during the reaction is what causes the bubbles in the flask.
- When the carbon dioxide gas reacts with lime water (Ca(OH)2), it forms calcium carbonate (CaCO3) which is insoluble and causes the lime water to turn milky.

Correct Answer:
- The correct answer to the question is option 'B' which states that the reactants in the flask are magnesium carbonate and hydrochloric acid.
- This combination of reactants produces the observed results of gas bubbles and milky lime water.
