Recommendation C is most appropriate.
Rebalancing of tax-exempt portfolio is unencumbered by tax considerations, and rebalancing maintains the desired level of risk. The balancing range for taxable account can be wider than that of tax-exempt account to minimize avoidable taxes and the after tax equity return‘s volatility will be lower(因为预期equity 会继续涨,所以短暂偏离risk toleranced可以得到更高的税后return对吗?).
