The normal level of illumination in a given area is described by which term?

Explanation:
Ambient lighting describes the general background illumination of a space—the overall light level that allows you to move around and see clearly without focusing on any specific surface. It sets the baseline visibility in the area. Illuminance is the amount of light falling onto a surface (measured in lux or foot-candles), luminance is how bright a surface appears to the eye (a perceptual brightness of a surface), and brightness is a subjective impression of lightness or darkness. Since the question asks for the normal, overall light level in the area, ambient lighting is the best fit.
