Which of the following is a whorl pattern type?

Explanation:
Whorl patterns are fingerprint ridge flows that form a circular or spiral arrangement and contain at least two deltas. The plain whorl is a classic example of this pattern type, showing a circular/oval ridge pattern around a central area with two deltas. In contrast, the ulnar loop has ridges that enter from one side, form a loop, and exit on the same side with a single delta, so it’s not a whorl. Plain arches and tent arches are arches, with ridge lines rising and exiting on the opposite side and no deltas present.
