Answer:
The most dangerous type of volcano is the
active
volcano.
The least dangerous type of volcano is the
extinct
volcano.
Explanation:
Did the test
but here is the explanation if you want it,
We have 3 options, dormant, active, and extinct.
The extinct is obviously going in the least dangerous category because of its definition.
Now we have 2, dormant and active.
An active volcano is just flowing with lava, you know it's happening but in a dormant volcano, you don't know when it's going to happen which makes it more dangerous, you really didn't need that explanation but, oh well.
