Why it is correct
Numbering follows the conventional direction of buoyage, in from seaward, with even on red and odd on green.

Region B covers the Americas (North, Central and South), Japan, South Korea and the Philippines; lateral colours are reversed (GREEN to port and RED to starboard when entering), while keeping the same shapes (can to port, cone to starboard) and identical cardinal, isolated danger, safe water and special marks.

- b) Even numbers go on red.
- c) The direction is from sea to land.
