The answer is going to be letter A
Carbon dioxide is heavier than oxygen gas. It therefore displaces the oxygen gas around a flame. Without oxygen, the combustion reaction will stop and the flame will be put out.
Further Explanation:
In order for a combustion reaction to happen, three components must be present: fuel, oxygen, and heat to cause ignition. When one of these three is removed, the combustion reaction will stop.
CO2 fire extinguishers use the difference in mass of the CO2 and oxygen molecules to stop the fire. Since CO2 is heavier, it will displace any oxygen molecules that are around the flame. When this happens, the supply of the oxygen will be limited or cut-off and the fire will eventually be put out because of the lack of oxygen. This ability to displace oxygen is also what makes using CO2 as fire extinguisher quite dangerous for the user since it pushes away the oxygen that is needed for respiration.
Other ways to put out fire include spraying liquids that absorb the heat to avoid spreading the fire further or spraying substances that coat the fuel (flammable materials) to avoid contact with oxygen gas which can lead to further combustion.

False. they form slowly due to erosion and the minerals stay the same
The answer should be Tidal Lock (A), because this is when the event of the orbital position of an object (Earth) is matching the same rotation period as the other object (Moon). When these rotations are the same, the moon will always be facing the same direction as the Earth. I believe you made a typo because Tidal Rock is not even considered to be a term in science. It is not a Solar Tide (that isn't even concerned with the moon facing the Earth), magnetosphere isn't even related to the moon but its magnetic field, and a tidal "bulge" is the complete opposite and has the moon facing the completely opposite direction.
