B. Intensity

Explanation:

The Intensity of an earth quake refers to the noticeable and severity effects of damage on man made structures, natural(crops and livestock) and human life at different locations. To measure the intensity of an earthquake, the Modified Mercalli Intensity Scale is used and consists  of 12  levels of intensity(in roman numerals) that  rank the extent of damage based on observable effects with the higher levels based  on structural damage.  

A Level I -V1 Intensity on the scale will show slight damages to properties and treatable injuries to people, but going higher on the scale above VI  shows total damage and destruction to structures and human life.
