Correct answer: D — Vitamin K at birth

IM vitamin K (phytomenadione 1 mg for term, 0.5 mg for preterm) at birth is the standard of care in Australia to prevent vitamin K deficiency bleeding (VKDB). IM is preferred over oral due to superior protection against late VKDB (2-12 weeks). Oral vitamin K requires multiple doses and carries a small risk of missed doses and late VKDB.
