  1. CHONS

  2. COHNS

  3. COSHN

  4. HONCS

The correct answer is: COHNS

Human hair is primarily made up of the protein keratin, which is composed of carbon, hydrogen, oxygen, nitrogen, and sulfur. Therefore, the correct element order is C-H-O-N-S, making option B the correct answer. Option A is incorrect because the elements are not listed in the correct order. Option C is incorrect because it has an extra "S" at the end. Option D is incorrect because it has "HON" which is not in the correct order.
