依据现行的《国家一、二等水准测量规范》规定：一、二等水准测量的成果测段往返测高差不符值超限，应就可靠程度小的往测或返测进行整测段重测，其取舍原则正确的是______。
A．若重测的高差与同方向原测高差的不符值超过往返测高差不符值的限差，但与另一单程高差的不符值不超出限差，则取用另一单程高差
B．若同方向两高差不符值未超出限差，且其中数与另一单程高差的不符值亦不超出限差，则取同方向中数作为该单程的高差
C．若重测的高差与同方向原测高差的不符值超过往返测高差不符值的限差，与另一半单程的高差不符值超出限差，应重测另一单程
D．当超限测段经过两次和多次重测后，出现同向观测结果靠近而异向观测结果间不符值超限的分群现象时，如果同方向高差不符值小于限差之半，则取原测的往返高差中数作为往测结果，取重测的往返高差中数作为返测结果
E．若同方向两高差不符值未超出限差，其两同方向高差中数与另一半单程的高差不符值超出限差，应重测另一单程
