Final answer:
The treatment for surfer mustard or lewisite exposure is decontamination with water and removal of contaminated clothing. Antibiotics may be used for secondary infections, but they are not the primary treatment.
Step-by-step explanation:
The treatment for surfer mustard or lewisite exposure is decontamination with water and removal of contaminated clothing. Surfer mustard and lewisite are both chemical warfare agents that can cause severe skin and eye irritation. Decontamination with water helps to remove the chemicals from the skin and clothing, reducing further exposure and potential harm.
Oral or intravenous antibiotics may be used to treat secondary infections that can occur due to chemical exposure, but they are not the primary treatment for surfer mustard or lewisite.
Therefore, the correct answer is C) Decontamination with water and removal of contaminated clothing.
