You did not post the scenario
Are there options? Structure meaning skeleton or anatomy?
#19 due to weathering and erosion the rock from the stream was smoothened and without as much the rock from deep underground was/is very rugged and natural.
#18 Due to wind patterns the sand dunes are blew around and the sands shift and fly around with nothing to keep the sand in place the sand can go long distances or come long distances.

Answer:
Virion Release
Explanation:
Mechanisms for virus release from cells include cell death (lysis), budding, and exocytosis. The cytoskeleton can bestow a barrier to release and some unenveloped viruses encode proteins that intrude the cytoskeleton to allow dispersal of newly assembled virions.
