AFCAT Model Paper 2

The logic followed here is :
Figures P, Q, R and T are the same and can be obtained by rotating the figure.
Also, 3 L shaped lines in the Figure P, Q, R and T are in a consecutive manner but in figure S only 2-2 L shaped line is consecutive.
In figure 'S' such a pattern is not followed. Hence, 'S' is the correct answer.
