What is the relation between rem and mrem?

Explanation:
Rem and millirem use the same base unit of dose, with milli- meaning a thousandth of that unit. So a millirem is 1/1000 of a rem. That means one rem equals 1000 millirems. This is the only statement that matches the correct ratio. The other options would imply the rem is smaller than a millirem, or that a millirem is larger than a rem, or that the two are equal, which isn’t correct.
