Answer 1

Correct option is (c) Hollow-tiled floors

Easy explanation: Ribbed floors are also known as hollow-tiled floors. In this type of flooring, hollow tiles replace the lower part of the slab since concrete cannot bear the tension caused in the lower part of the slab. The use of hollow tiles also reduces the weight of the slab.
