Answer: (C)

Verified step by step guidance

1. Understand the concept of heritability: Heritability refers to the proportion of observed variation in a particular trait, such as personality, that can be attributed to inherited genetic factors in contrast to environmental ones.
2. Familiarize yourself with the Five-Factor Model (FFM) of personality: This model includes five broad domains or dimensions of personality, which are openness, conscientiousness, extraversion, agreeableness, and neuroticism.
3. Review the research on the heritability of personality traits: Numerous studies have shown that these personality traits have a significant genetic component, often estimated around 50% heritability.
4. Consider the cross-cultural aspect: The heritability of these traits has been found to be consistent across different cultures, suggesting a strong genetic influence that is not limited to a specific cultural context.
5. Conclude by recognizing that the correct answer, 'nearly 50%', reflects the general consensus in psychological research regarding the heritability of the five personality factors across various cultures.
