As we can see in the given problem figures that leftmost 2 designs of the first row and rightmost two designs of the last row are getting changed from the first figure itself.
The change in the design has a pattern where it changes from "cc" to "uu" then "uu" to "oo" and then goes back to "uu" and "cc".
Now rightmost 2 designs of the first row and leftmost 2 designs of the last row will start changing according to the above-stated pattern from the 2nd problem figure.
Similarly, 2nd row and 3rd-row designs will start changing from next figures according to the pattern mentioned already.
Hence, answer will be A
