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.
