Caustic soda is commonly known as sodium hydroxide with formula NaOH. Which of the following options correctly pairs the name with its formula?

Explanation:
Caustic soda refers to sodium hydroxide, which has the formula NaOH—one sodium atom paired with a hydroxide group (OH). This simple composition reflects a strong base used in cleaning and chemical processes. The other names correspond to different compounds: sodium bicarbonate is NaHCO3 (baking soda), and sodium carbonate is Na2CO3 (washing soda). Because caustic soda is specifically sodium hydroxide, the pairing Sodium hydroxide with NaOH is the correct one.
