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

Let's match the fingerprint terminology with their correct definitions.
A. Ridges: These are the fundamental features of a fingerprint. They are the raised portions of the skin. So, A matches with III.
B. Type Lines: These are the two innermost ridges that start parallel and then diverge to surround the pattern area of a loop or whorl. They define the boundaries of the pattern. So, B matches with I.
C. Delta: This is a triangular-shaped feature found in loops and whorls. It is located at or nearest to the point of divergence of the two type lines. So, C matches with IV.
D. Enclosure (or Lake): This is a minutia or ridge characteristic where a single ridge splits into two and then rejoins a short distance later, forming a small enclosed space. So, D matches with II.
The correct set of matches is A-III, B-I, C-IV, D-II.
