Answer: Positive

**Explanation:** When defining asset classes, it is essential that the paired correlations of assets within the same class are relatively high. This ensures that the assets are homogeneous and behave similarly under similar market conditions. A positive correlation (Option C) is correct because it indicates that the assets move in the same direction, which is a key characteristic of a well-defined asset class. Options A (Negative) and B (Zero) are incorrect because they imply either inverse or no relationship, which would not meet the criteria for a cohesive asset class.
