Show answer and explanation

Correct answer: (c) Acrylic is also called artificial silk as it is prepared from cotton but shines like silk.

Explanation

Rayon, made from wood pulp, is the fibre called artificial silk – not acrylic.

Acrylic is a synthetic fibre known as synthetic wool; so that statement is incorrect.

Cotton (absorbs moisture), polycarbonate (CDs) and Teflon (non-stick coating) are all correct.
