• C. Open-mindedness, Conscientiousness, Extraversion, Agreeableness, Neuroticism
• D. Openness, Conscientiousness, Extraversion, Agreeableness, Neuroticism

Answer: (D)

This question tests knowledge of the five-factor model of personality, the Big Five. OCEAN is the standard abbreviation for Openness to experience, Conscientiousness, Extraversion, Agreeableness, and Neuroticism. That exact set of terms is what the acronym represents, and it’s the convention used across psychology to describe five broad dimensions of personality.

Openness refers to curiosity and a preference for novelty and variety; Conscientiousness captures reliability, organization, and discipline; Extraversion describes sociability and energetic engagement with others; Agreeableness involves warmth, cooperativeness, and kindness; Neuroticism reflects emotional stability versus tendency toward negative emotions. The other options mix in terms like Introversion, Open-mindedness, or Optimism, which aren’t the standard labels in the Big Five, so they don’t match the established acronym.
