What happens when you attempt to compile and run the following code?#include <vector>#include <iostream>#include <algorithm>using namespace std;template<class T>struct Out {ostream & out;Out(ostream & o): out(o){}void operator() (const T & val ) { out<<val<<" "; } }; int main() { int t1[]={3,2,4,1,5}; int t2[]={5,6,8,2,1}; vector<int> v1(10); sort(t1, t1+5); sort(t2, t2+5); set_union(t1,t1+5,t2,t2+5,v1.begin()); for_each(v1.begin(), v1.end(), Out<int>(cout));cout<<endl; return 0;}Program outputs:

A. 3 2 4 1 5 6 8 2 1 0
B. 1 2 3 4 5 6 8 2 1 0
C. 1 1 2 2 3 4 5 5 6 8
D. 1 2 3 4 5 6 8 0 0 0 E. compilation error
