The correct answer focuses on the fact that the visibility and effectiveness of exit signage are paramount in life safety situations, which is why considerations such as horizontal arrows indicating the direction of egress, ready visibility for quick recognition, and the overall harmony with the aesthetics of the space all play crucial roles.

While the design elements, such as using a matte background for lettering, may have some value in terms of visual appeal or context within an interior design project, they are not fundamentally critical to the function of exit signage. The primary purpose of these signs is to ensure that they can be easily seen and understood, especially in emergency situations. This clarity and directness take precedence over aesthetic considerations like the background finish. Thus, the choice of a matte background is the least relevant factor in ensuring exit signage serves its intended life-safety function effectively.
