Answer 1

The best reason for the well-preserved fossils of whales and other organisms found in the southern parts of Mississippi is:

A Fossils are preserved in the rocks formed from the sediments deposited by rivers.

This option correctly explains that sediments deposited by rivers can create the conditions necessary for fossilization. The other options either present misleading information about weather conditions, volcanic activity, or erosion processes that are not conducive to fossil preservation in this context.
