Inland Rule 18 states that its provisions apply except where certain other Rules otherwise require. Which Rules create those exceptions?

Why B is correct

33 CFR §83.18 opens with the phrase 'Except where Rules 9, 10, and 13 (§§ 83.09, 83.10, and 83.13) otherwise require,' establishing those three Rules as the specific exceptions to the general hierarchy set out in Rule 18.
