Changing the intensity of a light in Unity primarily adjusts the brightness of the light source. Light intensity dictates how much light is emitted from the source, which directly affects the overall illumination in the scene, making objects appear lighter or darker based on that setting.

Increasing the intensity will make the light brighter, enhancing visibility in the environment, while decreasing the intensity will lower the brightness, resulting in a dimmer scene. This adjustment is crucial for creating desired moods, highlighting specific elements, or ensuring that gameplay remains clear.

The other options pertain to different aspects of lighting or other settings in Unity. For example, distance relates to how far the light can effectively illuminate, color pertains to the hue of the light, and angle deals with the direction the light casts shadows or illuminates objects. However, none of these factors directly modify how bright the light is, which is the primary function of light intensity.
