RBE stands for "relative biological effectiveness" and is not a unit of radiation dose. It is a measure of how much more biologically damaging one type of radiation is compared to another. The other options are all units of radiation dose. Rem (Roentgen equivalent man) and rad (radiation absorbed dose) are measures of the amount of radiation that is absorbed by a person, while roentgen is a measure of the ionizing ability of radiation.
