      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 Production of alpha particles and neutrons constitutes radioactivity. Correct Answer Incorrect Answer
      B Nuclear fusion does not involve the production of alpha particles, and neutrons. 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 an example to prove that the popular misconception that nuclear fusion does not involve radioactivity is wrong. Hence (1) is the correct alternative.  Thus, the correct answer is option 1.
