The correct answer is:
D. becomes crystallized
Explanation (very important for exams):
Viruses show living and non-living characteristics.
When a virus is in a non-living medium (outside a host cell), it behaves like a non-living thing
It can be crystallized, just like chemicals (this was first shown with the Tobacco Mosaic Virus)
This is a key proof that viruses are at the boundary of living and non-living things
Why others are wrong:
A. Dehydration is not the key concept tested
B. Viruses do not form spores
C. Viruses do not have flagella
🧠 Exam tip:
If you see:
“virus outside host”
Think: inactive + can be crystallized
