Solution
The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
A body is said to be brittle if any applying any external force, it breaks instantaneously. That is, for a brittle body, there is no noticeable prior change, before that it ruptures.So, there is no neck formation is a stress-strain curve of brittle materials.
