Correct Answer:

Solution : According to the given figures –
1. A lamp-shaped structure rotates 90° in the clockwise direction.
2. The letters are placed diagonally –
In Box 1, the letter F and G is placed diagonally in the northwest and southeast direction.
In Box 2, the letters are rotated in a clockwise direction and the letter H is skipped and F and G are changed to I and J. After rotating clockwise the letters I and J are placed diagonally in the northeast and southwest direction.
In Box 3, the letters are rotated in a clockwise direction and the letter K is skipped and I and J are changed to L and M. After rotating clockwise the letters L and M are placed diagonally in the southeast and northwest directions.
In Box 4, the letters are rotated in a clockwise direction and the letter N is skipped, and L and M are changed to O and P. After rotating clockwise the letters O and P are placed diagonally in the southwest and northeast directions.

So, following the above pattern, the required figure will be as follows –

Therefore, the figure in the fourth option is the required figure. Hence, the fourth option is correct.
