How does a white spot differ from a white dot?

A white spot is characterized by certain visual and textural attributes that can distinguish it from a white dot. When considering the tactile aspect, a white spot typically refers to a blemish or defect on a surface, such as a screen, that may not be felt when touched. This lack of a tactile sensation means it is likely due to underlying issues like dust, defect, or pixel contamination, rather than being a raised area or a physical particulate that could be sensed with a fingernail.

The other options suggest comparisons based on size, presence, and brightness, which may not accurately define or differentiate a white spot from a white dot, as these characteristics can vary and are not universally applicable to both terms. Understanding the distinction based on tactile feedback provides a clearer and more precise differentiation in this context.
