Simon is correct. The product of a rational number and an irrational number is always irrational, except in the case where the rational number is zero. In that specific case, the product would be zero.
To summarize:
- If the rational number is not zero, the result will be irrational.
- If the rational number is zero, the result will be zero.
Since Simon's statement about the product being irrational (assuming the rational number is not zero) aligns with the fact, he is the correct answer.
Thus, the answer is: Simon.
