  1. Three all-round lights (red-white-red) in a vertical line plus the anchor light(s) prescribed by Rule 30Correct
  2. B. Three all-round lights (red-white-red) in a vertical line only
  3. C. Two all-round red lights in a vertical line plus the anchor light(s) prescribed by Rule 30
  4. D. Three all-round lights (red-white-red) in a vertical line, masthead light, sidelights, and sternlight

Why A is correct

33 CFR §83.27(b)(i) and (b)(iv) require a RAM vessel at anchor to show the red-white-red vertical light cluster AND the anchor light(s) prescribed by Rule 30 (§83.30). Sidelights and sternlight are only added when making way, not at anchor.
