What is the output of this program?

#include <iostream>
    #include <iterator>
    #include <vector>
    using namespace std;
    int main () 
    {
        vector<int> NewVector;
        for (int k = 1; k < 6; ++k) 
            NewVector.push_back(k * 10);
        ostream_iterator<int> out_it (cout,", ");
        copy ( NewVector.begin(), NewVector.end(), out_it );
        return 0;
    }

1. 10,
2. 10, 20,
3. 10, 20, 30,
4. 10, 20, 30, 40,
5. 10, 20, 30, 40, 50,

Correct Option: E

In this program, We are producing the values by vector and printing it by using ostream iterator.
