    Hi! What is the difference between A and E?

    Hi, the passage uses mechanism to describe the way cut which radiation happens. D is not what the author meant by mechanism, they are not talking about the specific isotopes but instead the general way that it happens. We are talking about the physical processes that make radiation happen, rather than the scientific theory behind it, so it is not E.
