Question

Match the LIST-I with LIST-II 

LIST-I	LIST-II
A. Ridges	III. The raised portion of the friction skin of the fingers
B. Type Lines	I. Two most inner ridges which start parallel, diverge and surround or tend to surround the pattern area
C. Delta	IV. The ridge characteristics nearest to the point of divergence of type lines
D. Enclosure	II. A single ridge bifurcates and reunites to enclose some space

• A. A - III, B - II, C - I, D - IV
• B. A - IV, B - II, C - III, D - I
• C. A - III, B - I, C - IV, D - II
• D. A - III, B - I, C - II, D - IV

Hint:

Visualize the fingerprint pattern: \textbf{Ridges} are the hills. \textbf{Type Lines} are the diverging highways around the main pattern. The \textbf{Delta} is the triangular interchange where the highways split. An \textbf{Enclosure} is a small traffic island where a road splits and rejoins.

Answer 1

The Correct Option is C

Match fingerprint terms to their definitions.
A. Ridges: The raised parts of the skin, which are the core fingerprint features. A matches III.
B. Type Lines: The two innermost ridges that begin parallel, then separate to enclose the loop or whorl pattern. They outline the pattern area. B matches I.
C. Delta: A triangular shape in loops and whorls, found near where the type lines diverge. C matches IV.
D. Enclosure (or Lake): A ridge characteristic where a single ridge splits, then rejoins, creating an enclosed space. D matches II.
The correct matches are: A-III, B-I, C-IV, D-II.
