This question was addressed to me in an interview.

My question is based upon Reinforced Earth topic in section Reinforced Earth and Geotextiles of Geotechnical Engineering II

Answer 1

Correct choice is (c) skin

For explanation I would say: The wall facing element is provided at the free boundary of a reinforced earth structure. This is done to provide some form of barrier and these elements are known as skin. These elements can be flexible or stiff.
