Final answer:
The temporary frame that appears around a selected object to show its dimensions and can be toggled from the View Menu is called a Selection frame.
Step-by-step explanation:
The temporary frame around a selected object that shows the object's outer dimensions and can be hidden or shown from the View Menu is known as a Selection frame (option C). When an object is selected in a graphics design program or similar software, the selection frame appears around it to indicate the area of the object. This frame is useful for aligning, moving, or transforming the object, and its visibility can usually be toggled in the program's view settings.
