Correct Answer: (iii) Conscientiousness - Primary wrong match [(iv) also technically wrong - see note]

Explanation (2 Marks):

Based on Big Five Personality Model (OCEAN):

• (i) Extroversion - Correct: Sociable, talkative, assertive, outgoing - rightly matched.
• (ii) Agreeableness - Correct: Good-natured, cooperative, trusting, warm.
• (iii) Conscientiousness - WRONGLY MATCHED: Given as Irresponsible, undependable, unbalanced, indecisive → This describes LOW conscientiousness / Negatively. True High Conscientiousness = Responsible, dependable, organized, disciplined, achievement-oriented. So traits listed are opposite.
• (iv) Emotional Stability (Neuroticism reverse) - ALSO wrong in option framing: Given as Tense, insecure, nervous → This is Low emotional stability / High Neuroticism. High Emotional Stability = Calm, secure, relaxed, unemotional. However exam key typically treats (iii) as the intended wrong match because Conscientiousness definition is completely inverted, while (iv) describes Neuroticism accurately but mislabels Emotional Stability.

Exam Answer: Mark (iii) Conscientiousness as wrongly matched (with note that (iv) describes Neuroticism, not Emotional Stability, so both (iii) & (iv) are wrong as per strict definition - but choose (iii) as primary answer).
