All the statements in the question are correct.

Statement 1: Baking soda, or sodium bicarbonate, is indeed used in fire extinguishers. It releases carbon dioxide gas when heated, which helps to suffocate the fire and prevent it from spreading.

Statement 2: Quicklime, or calcium oxide, is used in the manufacture of glass. It is one of the key ingredients which are melted together to produce glass.

Statement 3: Gypsum is used in the manufacture of Plaster of Paris. When gypsum is heated, it loses some of its water content and turns into Plaster of Paris, which is a quick-setting material used in construction and art.

Therefore, option 4 is the correct answer as it includes all the correct statements.
