ನೀಡಲಾದ ಆಯ್ಕೆಗಳು 1, 2, 3, 4 ರಿಂದ ಆಕೃತಿ X ಅನ್ನು ಪೂರ್ಣಗೊಳಿಸಿ.

In figure X each 2 × 2 block in the bottom half is the block above it turned through 180°: the bottom-left block is the top-left block turned upside down (the filled circle moves from top-left to bottom-right, and so on). Turning the top-right block through 180° gives empty triangle, filled diamond over empty circle, filled square, which is option 1.
