Final answer:
A fingerprint pattern with ridges that enter on one side and exit out the opposite side is called a Whorl. Whorl patterns form circular or spiral patterns with ridges that start on one side and curve around, exiting on the opposite side.
Step-by-step explanation:
The fingerprint pattern with ridges that enter on one side and exit out the opposite side is called a Whorl. In a whorl pattern, the ridges form circular or spiral patterns. When looking at a whorl fingerprint, you will see ridges that start on one side and curve around in a circular or spiral shape, exiting on the opposite side.
An example of a whorl fingerprint pattern is when the ridges form a circle in the center with two or more deltas (triangular patterns) on either side. Whorls can be further categorized into plain whorls, central pocket loops, double loop whorls, and accidental whorls.
The fingerprint pattern described in the question, where ridges enter on one side and exit out the opposite side, corresponds to the c) Loop pattern in fingerprint analysis. A loop is a type of fingerprint pattern that features ridges that flow inwards, recurve, and flow back out the same way they came in. This pattern contrasts with an arch, which flows in one side and out the other without recurving, a whorl, which consists of circles or spiral patterns, and a delta, which is characterized by a triangular ridge pattern.
