Consider a figure completion matrix where the pattern follows a standard quadrant reflection. If the top-left quadrant mirrors horizontally into the top-right quadrant, which configuration describes the correct missing bottom-right quadrant if it mirrors the bottom-left quadrant horizontally ?

In standard non-verbal pattern completion matrices exhibiting bilateral or horizontal symmetry, the left sections mirror perfectly onto their corresponding right sections across the central vertical axis. Therefore, the missing bottom-right quadrant must be a exact horizontally inverted reflection of the bottom-left quadrant.
