What is the output of this program?

#include <iostream>
    using namespace std;
    template<class T = float, int k = 5> class N
    {
        public:
        N();
        int value;
    };
    template<> class N<> 
    { 
        public: N(); 
    };
    template<> class N<double, 10>
    { 
        public: N(); 
    };
    template<class T, int k> N<T, k>::N() : value(k)
    {
        cout << value;
    }
    N<>::N() 
    {
        cout << " Out of ";
    }
    N<double, 10>::N() 
    {
        cout << "10" << endl;
    }
    int main() 
    {
        N<int, 8> x;
        N<> y;
        N<double, 10> z;
    }

1. 10 out of 8
2. 8
3. 10
4. 8 out of 10
5. None of these

Correct Option: D

In this program, We are defining three templates and specializing it and passing the values to it and printing it.
