Option by option

  • A. Excess cementum growth

    Excess cementum growth is less appropriate because it does not match the stated caries feature.

  • B. Pulp calcification

    Pulp calcification may be useful in another context but is not supported by this scenario.

  • C. Acid-mediated enamel demineralization (correct)

    Correct. Acid-mediated enamel demineralization is the most appropriate interpretation of the key information.
