The fruit that most closely resembles the liver in appearance is the persimmon.
The persimmon, particularly the Hachiya variety, has a distinctive shape and color that is reminiscent of the human liver. Its deep orange hue and rounded, slightly elongated form with a slight indentation at the top bear a striking resemblance to the liver's appearance.
While this resemblance is purely visual, it's important to note that the persimmon and the liver share no biological or functional similarities.
