有以下程序
#include <iostream>
using namespace std;
_______________________
void One(float one)
{ cout<<"1"<<endl; }
void Two(float two)
{ cout<<"2"<<endl; }
void Three(float three)
{ cout<<"3"<<endl; }
int main()
{ float i=1,j=2,k=3;
function = One;
function(i);
function= Two;
function(j);
function = Three;
function(k);}
请为横线处选择合适的程序使得程序的运行结果是123 ( )
B.
void *function(float);
D.
void (*function)(float);
