Puzzle 4

H - One segment is rotated each time from the first column in a row to the second. From the second to the third column, the segment directly opposite the previously rotated segment is then rotated to reflect the initial segment.

Puzzle 10:

I think it is A. My reasoning behind this is that they are doing a series of inversions to get the next figure (row and columnwise). So by applying the same inversions to row 2 column 3 and row 3 column 2, we get the circle.
