Consider the following C functions in which size is the number of elements in the array E:
int MyX(int *E, unsigned int size){
 int Y = 0;
 int Z;
 int i,j,k;
 for(i = 0; i < size; i++)
       Y = Y + E[i];
 for(i = 0; i < size; i++)
   for(j = i; j < size; j++){
     Z = 0;
     for(k = i; k <= j; k++)
        Z = Z + E[k];
     if(Z > Y)
        Y = X;
   }
   return Y;
}
The value returned by the function MyX is the
A
Maximum possible sum of elements in any sub-array of array E.
B
Maximum element in any sub-array of array E.
C
Sum of the maximum elements in all possible sub-arrays of array E.
D
The sum of all elements in the array E.
