The correct answer is D. Permethrin
Correct Answer Explanation
Patients with allergies to plants in the Asteraceae or Compositae family (chrysanthemum, ragweed, sunflower, artichoke, arnica, daisy, and marigold) should not be given permethrin, as it may cross react. The relevant potential allergen is sesquiterpene lactone.

The remaining answer choices will not cross react in a patient with a sunflower allergy.
