The correct answer is - b. African.
The African tectonic plate will move the most of all tectonic plates. It is moving into a northeastern direction, and it is pushing towards the western part of the Eurasian tectonic plate and it is squeezing the Arabian tectonic plate between itself and the Eurasian tectonic plate. Because of this movement, the African tectonic plate in a relatively small amount of time (geologically speaking) will merge with Europe, and since both of the plates are of same density a large mountain range will start to form because of the pressure between the two plates. Also, the Mediterranean Sea will be cut of from the Atlantic Ocean and it will dry out.
Answer:
The main reason why mountains are rarely populated is because of the harsh climate that are dominating in those areas. On the other side, another important reason is that mountainous areas are not fertile enough and people are not able to grow crops. Lack of resources therefore is obliging people to move from the mountains to lower terrains.
Explanation:

For example, Chinese civilization developed in the valley of Yangtze and Huang He and not Himalayas.
