某多层钢筋混凝土框架结构办公楼，抗震等级二级，首层层高4.2m，其余各层层高为3.9m，地面到基础顶面1.1m，柱网7.5m×7.5m，柱架柱截面尺寸600mm×600mm，框架梁截面尺寸为300mm×600mm(y方向)、300mm×600mm(x方向)，如图所示。首层中柱，柱底截面在x方向地震作用下的荷载效应与地震作用效应组合的内力设计值(已考虑二阶效应)为：M=800kN·m，N=2200kN，V=369kN，受力纵筋采用HRB400级，箍筋采用HRB335级。柱采用C30混凝土，梁采用C25混凝土。取a_s=a_s'=40mm。

假定已考虑侧移影响的该中柱上、下端截面沿x方向的组合弯矩、轴力设计值分别为：M₁=-600kN·m，N₁=2000kN，M₂=750kN，N₂=2200kN，试问，该中柱的控制截面的弯矩设值（kN·m），与下列何项数值最为接近，构件的计算长度近似数为l_c=5.3m。（）

A．750

B．770

C．800

D．850
