Study the figures given below:

From the figures given below, choose the figure that will be most suitable to continue the pattern given above.

The logic followed here is:​

For the "" element → 

• Shaded triangle region (part) - Alternately shifting to the immediate next triangle part in the clockwise direction.
• Increasing shaded triangle region - Alternately increasing shaded triangle region to the immediate next triangle part in the clockwise direction.

Thus, the final series is :

Hence, the correct answer is "Option - (4)".
