They will never go instinct because they grow everywhere

1- A species can migrate over long distances because they have metabolisms suitable for that, adaptation mechanisms to withstand different adversities. They usually do it to be able to reproduce in ideal climaxes or feed on certain living things or plant species.
2-The existence of oil fields, or oil towers for the manufacture of fuel.
3-Implement electric cars or batteries that do not depend on fuels such as diesel, naphtha.
Explanation:
In this exercise it is good to highlight that during the migration of animals of different species their numbers decreased both to reach the territory to which they migrate and by human intervention in nature in a harmful way.
A best fit line is a straight line so it can't connect to every dot on the graph. If there were many points everywhere, the line would zigzag to much.

For D, the line does not necessarily miss every one on purpose; a data point could be a part of the average.
