Correct option is D

All vertical line is place on top step by step-
In the 1st figure 4 vertical line in which one line shift in the second’s figure top horizontal lines become 2+1 = 3 lines. Similarly, as in the figure in 3 and 4. In the end next figure total no of horizontal line will be 6 and no vertical line.
Therefore, the correct option is (d).
