The set of all possible observations about a specified characteristic of interest is referred to as a population. A frame is a list of individuals or objects from which a sample is drawn, and a multinomial data set is a specific type of data with multiple categories and outcomes. An observational study is a type of research design in which the researcher observes and collects data but does not intervene or manipulate any variables. None of these options fully describe the set of possible observations about a characteristic of interest, so D is the best choice.
