Option by option

  • A. Acid-fast bacillus

    Acid-fast bacillus has another context but is not the most appropriate answer here.

  • B. Gram-positive coccus cluster

    Gram-positive coccus cluster does not fit the stated bacteriology relationship.

  • C. Comma-shaped rod (correct)

    Correct. Comma-shaped rod matches the decisive point in this scenario.

  • D. Spore-forming coccus

    Spore-forming coccus is unsupported by the mechanism or clinical clue in the stem.
