Which of the following statements are not correct?
a) Shearing stress is possible in liquids but not in gases
b) Elastomers are class of solids that do not obey Hooke's law
c) Elastic limit is the property of material of body where as elasticity is the property of a body
d) Bulk modulus of most of the solid material is zero.

A body regains its original shape after removal of external force , by virtue of elasticity.Elasticity and elastic limit both are properties of material, not of the body.

Modulus of rigidity for liquid and gases is zero.so shear stress is not possible in liquid and gases.

Bulk modulus (K) = - ΔP / (ΔV/V)

If K = 0 , Δv will be infinity.

Hence option - (4) is right.
