Consider the figures given below in a 3x3 matrix pattern. To fit the question mark, the correct answer is

Correct Option: Solid Circle

In this 3x3 matrix pattern, we observe two main attributes for each row and column: 1. Shape type: Each row and column contains exactly one Triangle, one Square, and one Circle. 2. Shading style: Each row and column contains exactly one shape with vertical lines/empty, one shape that is half-shaded, and one shape that is fully shaded (solid). In the third row: - The first shape is a Triangle with lines (or empty). - The second shape is a half-shaded Square. - Therefore, the missing third shape (at the question mark position) must be a Circle to complete the shape set, and it must be fully shaded (Solid Circle) to complete the shading set. Thus, the correct answer is a Solid Circle, which corresponds to option B. Other options are incorrect as they do not satisfy these row-and-column pattern rules.
