Final answer:
Option buttons are screen messages that provide choices or commands to the user in a graphical user interface.
Step-by-step explanation:
Option buttons are screen messages that provide choices or commands to the user. They are typically used in graphical user interfaces (GUIs) to present a set of options to the user, who can then select one by clicking on the respective button. These buttons are represented by text or icons and guide users on what action to take next.
For example, if you are using a software program and a message appears asking you to choose an option like 'Save,' 'Okay,' or 'Cancel,' those are option buttons. They help the user navigate through different actions or choices within a program or interface.
In the given question, the statement that option buttons are screen messages that tell you what command to choose next is true.
