Option 1 states that baking soda is used in fire extinguishers. This statement is correct. Baking soda, also known as sodium bicarbonate, is commonly used as a fire extinguishing agent. When it is heated, baking soda releases carbon dioxide gases, which helps to smother the flames and suppress the fire.

Option 2 states that quicklime is used in the manufacture of glass. This statement is also correct. Quicklime, also known as calcium oxide, is a key ingredient in the production of glass. It is added to the glass mixture to lower the melting point and improve the clarity of the glass. Quicklime reacts with silica, the main ingredient in glass, to form calcium silicate, which gives strength and stability to the glass structure.

Therefore, both statements 1 and 2 are correct. Baking soda is used in fire extinguishers and quicklime is used in the manufacture of glass. The correct answer is option 3, "Both 1 and 2."
