(b) If both assertion and reason are true but reason is not the correct explanation of assertion.
(c ) If assertion is true but reason is false.
(d) If assertion and reason are false.
Q. Assertion: For small deformation, the stress and strain are proportional to each other.
Reason: A class of solids called elastomers does not obey Hooke's law.
Reason: A class of solids called elastomers does not obey Hooke's law.

Answer

B

Explanation

`StresspropStrai n`
or `stress=Kxxstrai n`
Where k is the proportionality constant and is known as modulus of elasticity.
