B Correct answer
Explanation

The unique pattern of thin lines on fingertips is called fingerprints. These are friction ridge patterns unique to each individual, formed during fetal development and used for identification. Fingerprints remain unchanged throughout life and are classified into loops, whorls, and arches. They are not called grooves, finger lines, or impressions in scientific terminology.
