Step 1: Analyze the shapes in the grid.
The top row has a circle and a square. The bottom row has a circle and a blank space (likely a square by column consistency).
Step 2: Analyze the internal patterns and their relationship to the shapes and positions.
Top-left (Circle): Orthogonal lines.
Top-right (Square): Dots aligned orthogonally.
Bottom-left (Circle): Diagonal lines.
Step 3: Deduce the internal pattern for the bottom-right square based on a diagonal theme.
The 'X' in the bottom-left circle suggests a diagonal theme for the bottom row's internal elements.
Step 4: Evaluate the alternatives.
Alternative (1), a square with diagonally arranged diamonds, fits this "diagonal" theme for the bottom row, and the outer shape (square) is consistent with the column.
