Final answer:
The Amarna style in Egyptian art is characterized by the representation of pharaohs with elongated heads and exaggerated features.
Step-by-step explanation:
The distinctive Amarna style in Egyptian art is best explained by the representation of pharaohs with elongated heads and exaggerated features (Option C). During the Amarna Period, the art shifted to depict figures with elongated necks, sloping foreheads and noses, prominent chins, large ears and lips, and spindle-like arms and calves. This style was a departure from the earlier Egyptian art, which portrayed men with chiseled bodies and had a more idealistic quality.
