Which among the following is known as quicklime?
Detailed Explanation:
Quicklime is the common name for calcium oxide (CaO), produced by heating limestone (CaCO₃) to drive off carbon dioxide.
Ca(OH)₂ is slaked lime (formed when quicklime reacts with water), CaCl₂ is calcium chloride, and CaCO₂ is not a valid chemical formula.
Therefore, CaO is quicklime, making Option 4 the correct answer.
