Concept:Intra‑individual differences refer to variations in abilities, traits, or performance within a single person across different areas (e.g., a student scoring high in games but low in academics). In contrast, inter‑individual differences compare two or more people.
Explanation:The question asks for an example of intra‑individual differences, which involve only one individual. Let us examine each option:
- Option A compares the performance of two persons (A and B) – this is inter‑individual.
- Option B compares learning speed between two persons – again inter‑individual.
- Option C describes that person A, though interested in both academics and games, always excels only in games. This shows variation within the same person (A) across different traits (academics vs. games) – clearly intra‑individual.
- Option D compares two persons’ temperaments – inter‑individual.
Therefore, only Option C fits the definition of intra‑individual differences.
Answer:Option C –
Though having interest in academics and games 'A' always used to excel in games.
