What will be the value of the array after this code executes?

NaturalNumber[ ] array = new NaturalNumber2[4];
NaturalNumber count = new NaturalNumber2(1);
for (int i = 0; i < ; i++) {
array[i].copyFrom(count);
count.increment( );
}

*a.* array = { 0, 0, 0, 0 }
*b.* array = { 1, 2, 3, 4 }
*c.* array = { 4, 4, 4, 4 }
*d.* there is an error in the code that will cause a runtime error
