【单选题】
某公司接到一栋大楼的任务，经过分析决定将大楼的四层任务分别交给甲、乙、丙、个项目经理，每人负责一层任务，每层面积为10000。任务由同一个施工队施工，该工程队有5个施工组。甲经过测算，预计每个施工组每天可以铺设完成200，于是估计任务完成时间为10天，甲带领施工队最终经过14天完成任务；施工前咨询了工程队中有经验的成员，经过分析之后估算时间为12天，乙带领施工队最终经过13天完成；丙参考了甲、乙施工时的情况，估算施工时间为15天，丙最终用了21天完成任务；前三个施工队的工期代入三点估算公式计算得到估计值为15天，最终丁带领施工队用了15天完成任务。以下说法正确的是（45）。
A.
甲采用的是参数估算法，参数估计不准确导致实际工期与预期有较大偏差
B.
乙采用的是专家判断法，实际工期偏差只有1天与专家的经验有很大关系
C.
丙采用的是类比估算法，由于此类工程不适合采用该方法，因此偏差最大
D.
丁采用的是三点估算法，工期零偏差是因为该方法是估算工期的最佳方法
