In photography, a blank background typically serves what purpose?

A blank background is designed to enhance the foreground subject by eliminating distractions and allowing the viewer to focus solely on the main point of interest in the photograph. Without competing elements or clutter, the subject stands out more prominently, which can create a stronger emotional connection or convey a clearer message. This technique is especially useful in portrait and product photography, where the aim is to highlight features without visual interruptions.

Other choices do not align with the fundamental principles of photography. For instance, using a blank background is not aimed at creating distractions, filling up space unnecessarily, or darkening the image. Instead, it provides a clean canvas that supports the subject's visual presence, making option B the most appropriate answer.
