Step1: Analyze the first - pair pattern

In the first pair, each of the four circular elements in the figure changes its shading pattern. The black - shaded circle becomes white, the white - shaded circle becomes cross - hatched, the cross - hatched circle becomes grey - shaded, and the grey - shaded circle becomes black.

Step2: Apply the pattern to the second pair

Applying the same pattern to the second figure in the second pair, the black circle should become white, the white circle should become cross - hatched, the cross - hatched circle should become grey - shaded, and the grey - shaded circle should become black.
