Answer: Equal-weighted indexes exclusively

**Explanation:** - **Option A (Incorrect):** Price-weighted indexes do not require rebalancing because the weight of each constituent security is determined solely by its price, which does not necessitate adjustments. - **Option B (Correct):** Equal-weighted indexes are regularly rebalanced because the weights of constituent securities change as their market prices fluctuate. This ensures that the weights remain equal over time. - **Option C (Incorrect):** Price-weighted indexes are not rebalanced, as their weights are price-determined, making this option incorrect.
