Detailed Solution

On applying load on lead and rubber wires of same cross-sectional area, the strain produced in lead is much less than rubber wires. Now from the relation,

Y = Young's modulus

or Y = $\frac{stress}{strain}$

The Young's modulus of elasticity is greater for lead wires. Hence, lead is elastic than rubber.
