Which of the following is one of Isaac Asimov's "Three Laws of Robotics"? A. A robot must not permit itself to act on emotion when logic would dictate otherwise. B. Robots should not expect to hold the same rights as humans. C. A robot may not carry out tasks that would make humans themselves irrelevant. D. A robot must protect itself unless such protection requires it to harm a human.

 The correct answer is D. A robot must protect itself unless such protection would conflict with the First or Second Law.

Extra: Isaac Asimov was a science fiction author and biochemistry professor best known for his works on robotics and artificial intelligence. He proposed the "Three Laws of Robotics" which were designed to ensure that robots would behave ethically and safely around humans. These laws are:

1. A robot may not injure a human being or, through inaction, allow a human being to come to harm. 2. A robot must obey the orders given it by human beings except where such orders would conflict with the First Law. 3. A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.

These laws have become a staple in discussions about the ethics of artificial intelligence and guide modern-day thinking about how robots and AI should interact with humans. Asimov used these laws as a central theme in many of his stories, exploring the complex scenarios that could arise from the interactions of robots with these guidelines embedded in their programming.
