PLEASE HELP
The diagram below shows a portion of the geologic time scale.
Picture shows a geologic scale, there is a key that indicates bya = billion years ago and mya = million years ago. The geologic scale shows the first box labeled '4.6 to 4.0 bya' on top and 'Rocks are formed' within the box, second box labeled '4.0 to 3.5 bya' on top and 'Microscopic life appears' within the box, third box labeled '3.5 to 2.5 bya' on top and 'Atmosphere with oxygen formed' within the box, fourth box labeled '2.5 bya to 370 mya' on top and 'Land animals appear' within the box, fifth box labeled '370 to 250 mya' on top and 'Single giant landmass formed' within the box, and sixth box labeled '250 to 120 mya' on top and 'Flowering plants appear on Earth' within the box.
Based on the time scale, which of these inferences is most likely correct?
land animals created the first oxygen molecules
flowering plants created the first oxygen molecules
rock formation started after microscopic life appeared on Earth
the atmosphere was formed after microscopic life appeared on Earth
