Question

Which type of floor does not allow rainwater to seep into the ground?

• A. Cemented floor
• B. Marble floor
• C. Limestone floor
• D. None of the above

Answer 1

The correct option is C Limestone floor

• Limestone is a sedimentary rock composed primarily of calcium carbonate($CaC{o}_3$) in the form of the mineral calcite.
  
• Limestone tiles are made of natural stone, and it's one of the most affordable options if you want to avoid artificial materials for your flooring.
• Limestone floor does not allow rainwater to seep into the ground because it is low porosity.
• So, the correct answer is 'Limestone floor'.
