Concept:The pattern uses opposite letters in the English alphabet (e.g., A-Z, B-Y, C-X) for both the top and bottom elements of each figure.Explanation:Look at the given figures. The top element in the first figure and the top element in the second figure are opposite letters. The bottom elements also follow the same opposite-pair rule. Apply this logic to the missing figure. Its top and bottom letters must be the opposites of the corresponding elements in the previous figure. Among the options, only Option 4 matches the required opposite pairs, completing the series consistently.
