If we want to create a class of planets, we could use the following $($base$)$ class:

class Planet:

def $\_\_$init$\_\_($self$,$ name, oas, mts$,$ cno$)$:

self.name $=$ name

self.orbits$\_$a$\_$star $=$ oas

self.mass$\_$to$\_$form$\_$sphere $=$ mts

self.cleared$\_$neighborhood$\_$orbit $=$ cno

Which selection would create a subclass of terrestrial planets for which we could input the primary component of its surface?
