    Question

    It is a popular misconception that nuclear fusion power

    is free of radioactivity; in fact the deuterium-tritium reaction that nuclear scientists are currently exploring, produces both alpha particles and neutrons. Which of the following can be inferred from the above?
    A Nuclear fusion does not involve production of alpha particles, and neutrons. Correct Answer Incorrect Answer
    B Production of alpha particles and neutrons constitutes radioactivity. Correct Answer Incorrect Answer
    C Nuclear fusion does not result in radioactivity. Correct Answer Incorrect Answer
    D The deuterium-tritium reaction is an example of nuclear fission. Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    The deuterium—tritium reaction is given as example to prove that the popular misconception that nuclear fusion does not involve radioactivity is wrong. Hence (2) is the correct alternative. (1) and (3) contradict the passage .(4) cannot be inferred from the passage.
