Which of the following is NOT a type of finger print?

Analyze the question: We are asked to find the option that is NOT a recognized fingerprint pattern.

Concept: Fingerprints are classified by the ridge patterns on the fingertips. The three basic types are:

• Arch: ridges enter on one side and exit on the other, forming a wave or tent shape.
• Loop: ridges enter, curve back, and exit on the same side.
• Whorl: ridges form circular or spiral patterns.

Some classification systems also recognize a fourth category, the composite (or "compound") pattern. It is a mix of the other types, so "compound" can count as a fingerprint type in some textbooks.

Step by step:

1. Arch is a basic fingerprint type, so it is not the answer.
2. Compound/composite is recognized in some systems as a mixed pattern, so it is not the answer.
3. Loop is a basic fingerprint type, so it is not the answer.
4. Whorl is a basic fingerprint type, so it is not the answer.
5. Simple is not a fingerprint classification. It is not a recognized pattern name in any standard system.

Answer: D. simple.

Tip: Remember A-L-W (Arch, Loop, Whorl) as the three main types. Composite/compound is the "mixed" extra. Any word outside this set, like "simple", is the odd one out.
