4.6 billion years ago - most likely hydrogen (H2) and helium (He)
probably rich in hydrogen compounds like methane (CH4), ammonia (NH3), hydrogen cyanide (HCN), water (H2O), and formaldehyde (HCHO). Also some N2, CO2 but LITTLE or NO free oxygen.
Molecules of H2 and He move really fast, especially when warm, that they eventually all escaped Earth's gravity and drifted off into space.
The answer is B. In a destructive plate boundary, the descending plate, usually the oceanic plate begins to melt as it descends below into the mantle. This forms magma that rises and erupts onto the overlying continental plate through fissures. This volcanic activity is responsible for geographical features such as the volcanic island arc, which lies parallel to the subduction zone.
