Explanation:

The assertion is true because of the property of ductility exhibited by metals. Ductility is the ability of a material to deform under tensile stress, which means that it can be elongated without breaking. Hence, a piece of metal wire will elongate when subjected to a tensile force.

The reason is also true because when a tensile force is applied to a metal wire, it causes the atoms in the wire to move apart, which increases the interatomic spacing. This happens because the force pulls the atoms in the wire away from each other, which leads to an increase in the distance between them.

Therefore, both the assertion and reason are true, and the reason explains the assertion.
