What does 'use of light' mean?

• A. Measuring light levels and glare in the area
• B. The speed of light affecting response times
• C. The use of natural light, artificial light and darkness advantage/disadvantage
• D. Lighting equipment and maintenance

Answer: (C)

Use of light means how lighting is applied in a space to support visibility, comfort, safety, and energy efficiency by leveraging natural daylight, artificial lighting, and periods of darkness. It covers how each source or absence of light can be used to shape tasks, mood, and energy use, along with the advantages and disadvantages of daylight, artificial light, and darkness. The best choice explicitly addresses this broad, practical use of light rather than focusing only on measuring light, the speed of light, or equipment and maintenance.
