Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
As the amount of carbon increases in a steel, if gets harder.
So, if there is low amount of carbon in the steel, then it will be more elastic. As an elastic materials shows a linear stress-strain relationship within elastic limit,so, steel will show the same.
