B. Australia and Antarctica were a single landmass in the past.
Explanation:
The most likely explanation for why the fossils of this plant are found on these two continents is that Australia and Antarctica were a single landmass in the past.
This evidence is vastly supported by the theory of plate tectonics originally, the theory of continental drift.
- Plate tectonics proposes that all land masses were once joined together as a single supercontinent called Pangaea.
- The region of Antartica and Australia were once joined as a single continental mass.
- The plant must have developed together at that time.
- When the continents moved apart, they still had the fossils.

PE equals KE when KE is 50%.
Like below:
E = PE + KE
E = 50 + 50
E = 100.
Remember, both KE and PE always have to add up to 100 so that is why PE is equal to KE when KE is 50% of energy.

Our solar system formed from a huge cloud of dust and gas called a
c. solar nebula
Based on the nebular hypothesis, our solar system formed from hydrogen gas and interstellar dust. The gas and the dust contracted and formed the early stage of the sun.
