II and III

If the avg is an odd number the sum is the avg * 5 = odd thus the sum is also odd.

III is also true because if the avg is an odd number the sum must be odd ... in order for the sum to be odd you need to start with an odd integer and end with an odd integer and odd - odd is even

1 doesnt hold

-1 0 1 2 3
