What comprises the "data values" in a variable?

The concept of "data values" in a variable refers to the specific information or data that the variable can hold and represent at any given time. In this context, the correct answer, which identifies a "list of states," aligns perfectly with the definition of data values. A variable typically embodies various conditions or states it can represent, often indicating different scenarios or statuses within a program or system.

For instance, if a variable is intended to depict the status of a device, the data values it holds might include states such as "on," "off," "standby," or "error." Each state signifies a particular condition that the variable is meant to track throughout its lifecycle.

Other options, while related to programming concepts, do not accurately align with the definition of data values in a variable. A list of actions would pertain more to what the system may execute rather than the current states it can represent. A list of conditions implies various conditions under which the variable might change, and a list of triggers relates to events that activate certain functions but does not directly describe the data values themselves. Therefore, the notion of "states" effectively encapsulates the role of data values in a variable.
