27 use the information and your knowledge of science to answer the question. a group of students was hiking along a riverbank in louisiana and found a fossil of a shell in the gravel. one student identified the shelled organism as an organism that once lived on the seafloor. which student best explains how the shelled organism fossil formed over time? a student b states that the organism must have traveled to the river from the ocean and that the fossil formed over the last few thousand years. b student c states that the louisiana area must have once been covered by the sea and that the fossil formed over hundreds of years. c student d states that the louisiana area must have once been covered by the sea and that the fossil formed over millions of years. d student a states that the organism must have traveled to the river from the ocean and that the fossil formed over the last few years.

Answer

Answer:

C. Student D states that the Louisiana area must have once been covered by the sea and that the fossil formed over millions of years.

Brief Explanation:

Fossils form over long - geological time scales (millions of years). The presence of a seafloor organism fossil in a non - marine area suggests the area was once underwater. Student D's explanation is consistent with geological and fossil formation knowledge.
