I had been asked this question during an internship interview.

I need to ask this question from Damp Proofing in chapter Building Construction of Basic Civil Engineering

Answer 1

Correct answer is (d) Damp Proof Membrane

To elaborate: DPM is a membrane material applied to prevent dampness. It can be used for a DPC (Damp Proof Course). An example is laying a polyethylene sheet under concrete slabs.
