[单选题]Actually_______
实际上_______
AThis method is feasible 该方法可行
BNot feasible because the median selection algorithm cannot be used for quicksort 不可行,因为中位数选取算法不能用于快速排序
CNot feasible, because the median selection algorithm for linear time is actually very inefficient 不可行,因为线性时间的中位数选取算法实际效率非常低
DNot feasible due to high space complexity 不可行,因为空间复杂度太高
