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 donot 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.

• Due to its elasticity, a body can return to its former shape after being subjected to an external force. 
• Elasticity and elastic limit are both material qualities, not bodily characteristics.
• For liquids and gases, the rigidity modulus is zero.
• Thus, liquids and gases cannot experience shear stress.

Hence the correct answer is only a, c and d.
