Answer:

b. The death toll from volcanic eruptions do not always correlate to exclusivity, and can be affected by human actions before and after the eruption.

Explanation:

Many volcanic eruptions don't kill anyone. This is because most active volcanoes are well-known to local residents, who give them appropriate respect.

Lahars are deadly, but so are pyroclastic flows, and releases of ash and/or poison gases. The two deadliest eruptions in recorded history caused death by starvation and tsunami.

The point of the paragraph was that the VEI was <em>not</em> directly related to the number of deaths.
