Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
Living organisms exhibit properties such as metabolism, growth, reproduction, consciousness, etc. They have their own specific form and structure. Thus, living organisms are considered as self-replicating, evolving and self-regulatory interactive systems capable of responding to external stimuli, sharing a common genetic material to a varying degree both horizontally and vertically.
Hence, both assertion and reason are true but the reason is not the correct explanation for assertion.
