Yes, oceans did not exist 4 billion years ago because Earth's atmosphere was too hot and it composed of gases that are toxic. It is only later when the Earth started to cool down that water began to surface on Earth and enabled the existence of many life forms that have evolved and became extinct through time.

Answer:

The geographic theme of movement is about movement of people from one region/country to another, as well as goods and even ideas.

Let's examine all the scenarios suggested here and see if they match the geographic theme of movement.

Ahmad's great-grandparents were originally from Afghanistan.

YES.  Ahmad's great-grandparents moved out of Afghanistan at some point.

Songs and movies made in India are very popular in Afghanistan.  

YES. The CDs and DVDs created in India travel to Afghanistan.

Afghanistan is east of Iran.  

NO. The countries won't move, at least their grounds won't move in our lifetime.

Afghanistan's rugged mountains provide protection for its people.  

NO, again, the mountains won't move significatively in our lifetime.

Much of Afghanistan's forests are being cut down for fuel.  

No. It's a transformation of the landscape, but that doesn't  implicate a movement from a country/region to another.  The chopped wood is most likely used very near the place it was cut.

Afghanistan exports wool to Turkey and India.

YES, exportation means transport of goods from one place to another.
