Answer:
The most likely factors that contributed to the changes in Lake Urmia are the population increase and increased water demand.
Explanation:
A is not correct because this lake, as all lakes, is not connected to the sea, so the sea levels can not influence its water levels.
B is not correct because if it was a case of regular floodings the lake would have gained more water, not lose it.
C is correct because the rapid rise of the population in Iran has led to much bigger usage of natural resources, including water resources.
D is not correct because the increased fish harvesting has no effect on the water depth or water volume of the lake.
E is correct because the increased water demand for different purposes is often the prime factor that leads to overexploitation of the water resources and often causing huge damage to them.
