Statement I: The speed of sound in solids is maximum though their density is larger than liquid.
Statement II: The coefficient of elasticity of solid is large.

Moderate

A

If both statement I and statement II are true and statement II is the correct explanation of statement I.
B

If both statement I and statement II are true but statement II is not the correct explanation of statement I.
C

If statement I is true but statement II is false
D

If both statement I and statement II are false

Solution

The velocity of sound in solid is given by $v = \sqrt{E / ρ}$ . Though $ρ$ is large for solids, but their coefficient of elasticity E is much larger (compared to that of liquids and gases). That is why v is maximum in case of solid.
