Answer: D
Notes:

The moon revolves around the Earth, and as it does, we see different angles of the moon’s illuminated surface. The moon doesn’t create its own light, but rather shines when it reflects the sun’s light. As the moon transitions from new to full and back to new again, it goes through several phases, marked by its recognizable crescent and gibbous (“bulging”) shapes, which are created by the moon’s own shadow. The moon phases are:

  • New moon
  • Waxing crescent
  • First quarter/Half-moon
  • Waxing gibbous
  • Full moon
  • Waning Gibbous
  • Third quarter/Half-moon
  • Waning crescent
  • New moon
