The circle below represents a planet. An earthquake occurs in the crust at the location of the red star. You have seismometers placed around the planet (black dots) that record this earthquake.  The P next to a station indicates that a direct P wave was detected by that seismometer.  An S next to a station prepresents that a direct S wave was detected.  What can we say about the interior structure of the planet based on this data?   A) There is a very large liquid outer core. B) There is a small solid inner core C) There is a small liquid core D) The planet is solid and contains no liquid layers
