The feature "Brilliance Control" is likely related to the adjustment settings for a display or lighting device, such as a computer monitor or screen. Its purpose is primarily to adjust the brightness and possibly other characteristics of the light being emitted. Here are the two most applicable options from the given choices:
(A) To illuminate light characteristics: This option fits because 'Brilliance Control' might allow for changing how brightly or dimly a light source shines, which directly affects the illumination characteristics.
(C) To reduce brightness to zero: This option is appropriate as 'Brilliance Control' would typically include the ability to dim the display or light source down to zero brightness, effectively turning off the light output.
It is important that the controls for such features are user-friendly, often using a slider or similar interface for ease of adjustment.
In summary, 'Brilliance Control' helps users manage the brightness levels of a device to suit their preferences or environment, ensuring comfortable viewing experiences.
