Pick up the correct statement from the following: A. The heating of a material to redness in contact with air, is known as calcination B. The property of lime by which it sets or hardens in damp places having no free circulation of air is called setting C. The product that remains after calcination of limestone, is called lime D. All the above

The correct answer is D. All the above.

Calcination is the heating of a material to redness in contact with air, or in the absence of air, to drive off volatile matter. The product that remains after calcination of limestone is called lime. Lime is a white or grayish-white powder that is used in a variety of applications, including construction, agriculture, and water treatment.

The property of lime by which it sets or hardens in damp places having no free circulation of air is called setting. This property is due to the reaction of lime with water to form calcium hydroxide, which is a solid.

Therefore, all of the statements in the question are correct.
