D. Liver

The core Amino acid metabolism principle identifies Liver as the best answer because it most directly explains the biochemical pathway or tissue response described in the stem.

Option by option

  • A. Kidney

    Kidney does not match the stated amino acid metabolism mechanism.

  • B. Spleen

    Spleen is relevant in another context but is not the best answer here.

  • C. Heart
