What will be the output for the given code?

 

#include <stdio.h> 

#include <stdbool.h> 

bool func1(int arr[], int n, int sum) 

    if (sum == 0) 

 return true; 

    if (n == 0 && sum != 0) 

 return false; 

    if (arr[n-1] > sum) 

 return func1(arr, n-1, sum); 

    return func1(arr, n-1, sum) || func1(arr, n-1, sum-arr[n-1]); 

bool func (int arr[], int n) 

{  

 int sum = 0; 

 for (int i = 0; i < n; i++) 

 sum += arr[i];  

 if (sum%2 != 0) 

 return false; 

 return func1 (arr, n, sum/2); 

int main() 

    int arr[] = {4,6, 12, 2}; 

    int n = sizeof(arr)/sizeof(arr[0]); 

    if (func(arr, n) == true) 

 printf("true"); 

    else

 printf("false"); 

    return 0; 

}

 

a) true

b) false

c) 4 6 2
