In the following questions, a statement of assertion is followed by a statement of reason. Mark the correct choice as (a) If both assertion and reason are true and reason is the correct explanation of assertion. (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.

Assertion: The metals of 4d and 5d greater entalpies of atomisation than the corresponding elements of the 3d series. Reason: The metal-metal bond in 4d and 5d series are stronger than those in the 3d series.

Assertion : If three identical bulbs are connected in series as shown in figure then on closing the switchs. Bulb C short circuited and hence illumination of bulbs A and B decreases. Reason : Voltage on A and B decreases
