Two wires \( A \) and \( B \) of same length are made of same material. The figure represents the load \( F \) versus extension \( \Delta x \) graph for the two wires. Then,
\( \mathrm{P} \)
(a) the cross-sectional area of \( A \) is greater than that of \( B \)
(b) the elasticity of \( B \) is greater than that of \( A \)
(c) the cross-sectional area of \( B \) is greater than that of \( A \)
(d) the elasticity of \( A \) is greater than that of \( B \)
