A wire is suspended from the ceiling and stretched under the action of a weight F suspended from its other end. The force exerted by the ceiling on it is equal and opposite to the weight.

(a) Tensile stress at any cross section A of the wire is $\frac{F}{A}$.

(b) Tensile stress at any cross section is zero.

(c) Tensile stress at any cross section A of the wire is $\frac{2F}{A}$.

(d) Tension at any cross section A of the wire is F.
