(c) the elastic property as well as the inertia property

EXPLANATION:

The speed of the sound in a fluid is V = √(B/ρ) and in a longitudinal solid rod V = √(Y/ρ) For extended solids, V is a complicated function of B as well as G (Shear Modulus). B, Y and G are measures of elastic properties and ρ is the measure of inertia property. Hence the speed of sound in a medium depends on the elastic as well as the inertia property, thus option (c).
