Identify the odd number: In 11, 8, 14, and 66, three are even (and composite), while one is an odd prime. Select the odd prime.

Introduction / Context:
The majority here are even composites; the outlier is an odd prime. Distinguishing parity and primality together solves the item fast.

Given Data / Assumptions:

• Set: 11, 8, 14, 66.
• Even numbers greater than 2 are composite.

Concept / Approach:
Check parity first, then apply quick prime tests to any odd candidates.

Step-by-Step Solution:

Verification / Alternative check:
Trial division up to sqrt(11) confirms its primality. Others have obvious factors of 2.

Why Other Options Are Wrong:
They are even composites, consistent with the majority property.

Common Pitfalls:
Confusing “odd” with “composite”; many odd numbers are prime.

Final Answer:
11 is the odd prime and the correct choice.
