The answer and the reasoning

B. Histamine

The core Inflammation principle identifies Histamine as the best answer because it most directly explains the biochemical pathway or tissue response described in the stem.

    Erythropoietin does not account for the central finding in this sample.

  • C. Insulin

    Insulin does not match the stated inflammation mechanism.

  • D. Thyroxine
