Which figure should replace the question mark (?) if the following series were to be continued? 

This question tests pattern recognition. Let's analyze the given series:

Observe that the pattern involves a rotation of the inner shape within the larger shape. Specifically, the inner shape rotates 90 degrees clockwise in each step.
Following this pattern, the inner square in the last figure should rotate another 90 degrees clockwise. This leads us to the correct answer:

Therefore, option 2 is the correct answer.
