Mercury is an element that is toxic to humans in high doses. How can humans reduce their risk of ingesting this element in harmful amounts?

A.) Humans could avoid eating animals at high trophic levels, as their bodies contain more mercury than those at lower trophic levels.

B.) Humans could avoid eating herbivores, such as plant-eating fish, as their bodies contain relatively high amounts of mercury compared with other animals.

C.) Humans could avoid eating animals at all trophic levels, which all have equal risk of containing mercury, while consuming only plants.

D.) Humans could avoid eating plants, as these contain especially high levels of mercury.
