Which trendline type best fits the data in the graphs of interatomic distance versus mohs hardness?

a.
linear

b.
exponential

c.
logarithmic

d.
the data are scattered and do not follow any trend.

a.  linear

Explanation:

Mohs scale is a qualitative ordinance scale i.e characterized by stretch-resistant minerals that are available through the hardness of science.  A mineral is pure samples of rocks. Its hardness is measured against the scale and as the properties of ordnance, scale measures the values from 1 to 10 in serial order of events. LIner fashion of measurement is followed in Mohos and interatomic distance being measured also changes with the properties that best fit this pattern of alignments.

The answer is c) people evacuated but almost all returned
