Introduction:

Segmentation is the movement, which is triggered by the chemicals, hormones, and physical stimulation. In this, circular muscle layers are involved.

Explanation of Solution

Segmentation is defined as the process of contraction of circular muscles in the small intestine, wherein the activities like churning of the digestive tract content and its fragmentation and mixing occur and it creates a more uniform mixture throughout. However, no net movement is produced in a particular direction.

Conclusion

Therefore, it can be concluded that the term segmentation can be correctly matched with option (c) churn and fragment digestive materials.
