Increased surface area increases the number of molecules that can be collected from the air. according to this information, which beetle antenna is best adapted for chemically sensing the air?

F

The question has attached diagram showing four choices F, G, H and J. According to the information the beetle antenna that is best adapted for chemically sensing the air is F because it has a much bigger surface area than the rest.  The number of molecules that can be collected from the air is higher using this antenna. 

some of your causes might be acidic rain or natural wildfires that cause the parks to be degraded
