Solution
The correct option is A Heavy water
Deuterium is much less likely to absorb neutrons than protium. As a result, more of the neutrons in a heavy water reactor are available to be absorbed by uranium than in a light water reactor. The result is that the uranium in a reactor does not need to be enriched in U-235; natural uranium can be used as fuel. This in turn means that a heavy water reactor can produce more energy per unit of uranium mined.
