Which statement best matches relative size magnification?

• A. The enlargement is based on moving closer to the observer.
• B. The size is increased through optical principles.
• C. Magnification is accomplished through electronics.
• D. The object is physically enlarged.

Answer: (D)

Relative size magnification means increasing the actual size of the object so its true dimensions are bigger, not just making it look larger from a different viewing setup. The statement that the object is physically enlarged fits this idea because it describes a real increase in the object's size, not just a change in how large it appears. Moving closer changes angular size, making it seem bigger without changing the object's true dimensions. Using optical principles or electronics can magnify the image or display you view, but the object itself isn’t physically bigger. Therefore, physical enlargement of the object best matches relative size magnification.
