To determine the fourth figure in the sequence, we need to identify the pattern in the figures provided:

1. Observe the sequence of figures:
   • The first figure contains a circle with an arrow pointing from the top left to the bottom right.
   • The second figure shows a circle containing a square with the arrow pointing from the bottom left to the top right.
   • The third figure has a circle with the arrow at a different angle.
2. Pattern identification:
   • The circle is consistent across all images.
   • The arrow in each image rotates in a specific direction and changes angles.
   • The presence of a square in the second figure suggests alternating patterns with shapes inside the circle.
3. Predicting the fourth figure:
   • The pattern suggests the alternating shapes inside the circle (none, square, none).
   • The fourth figure should contain a square again inside the circle to follow this alternating pattern.
   • The arrow should continue the established direction of rotation.

Based on the observed pattern, the correct fourth figure is:

This figure includes both the consistent element of the square and the clockwise rotation of the arrow.
