This is an example of vestigial structure.

Vestigial structures are structures (cells, tissues and organs) found in an organism that has lost most or all of its primitive function through evolution. The vestigial structure has performed vital functions in the organism in the past but as there are changes in species as a result of natural selection, the structure became less important until it no longer functions. A reduced nonfunctional digit on the paws of dogs known as a dewclaw is an example of vestigial structure.

The correct answer is Vestigial structure, and this is why:
a vestigial structure is a structure that has lost most of its ancestral function. So the reduced nonfunctional digit (dewclaw) would be considered a vestigial structure.

Answer:

Methemoglobinemia

Explanation:

Methemoglobinemia (also known as the blue baby syndrome), is a condition with multiple etiologies which is associated with the lack of oxygen in the blood. This syndrome affects the function of red blood cells by altering the amount of hemoglobin protein, which carries and distributes oxygen to the body. Methemoglobinemia may be acquired by exposure to drugs and/or toxins. In this regard, it has been shown that high levels of nitrates in the water may induce this syndrome in infants.
