有如下程序： #include＜iostream＞ using namespaee std； class Pair{ int m； int n； public： Pair(int i，int j)：m(i)，n(j){ } boot operator＞(pair P)const；//需在类体外给出定义 }； int main( ){ Pair pl(3，4)，p2(4，3)，p3(4，5)； cout＜＜(pl＞p2)＜＜(p2＞p1)＜＜(p2＞p3)＜＜(p3＞p2)； retum 0； } 运算符函数operator＞的功能是比较两个Pair对象的大小，当左边对象大时，返回true，否则返回false。比较规则是首先比较两对象的m成员，m大者为大；当m相等时比较n，n大者为大。程序输出0101，下列对运算符重载函数的正确定义是

A:bool Pair::operator＞(Pair P)eonst B:bool Pair::operator＞(Pair P) {if(m!=P.m)return m＞p．In；return n＞p．n；} {if(m!=P.m)return m＞p．m；return n＞p．n；} C:bool Pair::operator＞(Pair P)eonst D:bool Pair::operator＞(Pair P) {if(m＞p.m)return true；return n＞p.n；} {if(Ul＞p.m)return true；return n＞p.n；}
