Answer: The possible evolution of a cave formation is a.) soda straw > stalactite > column
Explanation:
The Soda straws represent the earliest growth of stalactites, these ones are known as tubular stalactites; they are hollow mineral cylindrical tubes that are formed of calcite.
When the hole at the bottom is blocked, or water begins flowing on the outside surface of Soda straws, then, a new formation is done, that is called Stalactite.
When a Stalactite joins to a Stalagmite, a new fomation is done, that is called Column.
