Which of the following is a defining characteristic of living organisms?
Ans: (d) Response to external stimuli
Explanation: The rest of the characters may not be apparent at every instance of time. But the response to external stimuli can always be confirmed as and when required. So, this is considered a defining characteristic of living organisms.
