Complete the following function:
/* copy string2 to string1 */
Void strcopy(char string1[], char string2[])
{
Int i = 0;
While (string2[i] != '\0')
{
String1[i] = string2[i];
I++;
}
____
}

A) return;
B) string1[i - 1] = '\0';
C) string1[i] = '\0';
D) string1[i + 1] = '\0';

To correctly copy a string in C, including its null terminator, you should assign the null character ('\0') to the next position in string1 after the last copied character. This ensures the copied string is properly terminated. Option C does this correctly by placing '\0' at the index `i`, which is right after the last copied character from string2.
