Final answer:
The lake marked by the letter C is likely simply referred to as a 'lake,' since it is at or connected to the level of the water table as opposed to a perched lake, which is above the water table.
Step-by-step explanation:
In the given scenario, the lake marked by the letter A is referred to as a perched lake, which is located above the water table. In contrast, the lake marked by the letter C being part of the landscape's lower area, hence it would likely be at the same level as the water table or may even directly contribute to it through groundwater recharge.
Furthermore, understanding the relationship between the water table and the lake and pond ecosystems is key to identifying such bodies of water. Lakes that are not perched typically interact with the groundwater system; either contributing to recharge when they are above the water table, or discharging from it when they are below.
