Consider the following about ductile and brittle materials: (i) Ductile materials have a large region between elastic limit and breaking point. (ii) Brittle materials show little or no plastic deformation. (iii) Mild steel is ductile while glass is brittle. (iv) Ductile materials cannot be used to make wires. Which are true?

Options

  1. A(i), (ii), (iii) only
  2. B(ii), (iii), (iv) only
  3. C(i), (iii), (iv) only
  4. D(i), (ii), (iii), (iv)

Correct answer

A. (i), (ii), (iii) only

Step-by-step solution

Statement (iv) is false-ductile materials (like copper, aluminium) are used to make wires.
