The correct answer is "increased activity of the right hippocampal formation".
Hippocampus is a brain area which is part of the limbic system and is located below the cerebral cortex. Humans have two hippocampi, one in each side of the brain. Hippocampus is responsible for the formation of long-term memories, by participating in the consolidation of short-term to long-term memory. It also plays a very important role in spatial memory and orientation.
The task that this experienced cab-driver is asked to perform is related to spatial navigation and orientation abilities. The right hippocampus has been shown to participate in the formation of memory for locations in specific environments, while the left hippocampus has been shown to be involved in autobiographical and episodic memory. As a result, the PET scan will show an increased activity of the right hippocampus.

Answer: Option (A) is the correct answer.
Explanation:
Beaches are the places which are part of shore of an ocean, sea, large river etc.
There are pebbles and sand at the shore of a beach. Waves of water in an ocean always change the ocean due to erosion and addition of sand.
It is the force acted by the wave that pushes or pull the sand in different directions every time the wave comes.
So we can conclude that the statement beaches are always changes due to factors such as waves adding and eroding sand best describes beaches.
Temporary changes would be weather, since it can change at any givin time another example would be tides coming in because they vary by day, or wet sand becoming dry sand!
