Vitamin K1 helps in cases of rodenticide poisoning by restoring normal blood clotting ability. Vitamin K is essential for the production of certain clotting factors in the blood. Rodenticides interfere with the body's ability to produce these clotting factors, leading to abnormal bleeding and potentially life-threatening situations. By restoring the body's normal clotting ability, Vitamin K1 can help to counteract the effects of the poison and prevent excessive bleeding. Options A (inducing vomiting) and B (neutralizing the poison directly) may help in other cases of poisoning, but they do not specifically address the issue of blood clotting. Option D (acting as an antihistamine) is not relevant to rodenticide poisoning. Therefore, the most correct answer is C.
