The mix ratio chlorine bleach solution for blood and body fluid cleanup and disinfection is

Explanation:
Disinfection after blood and body fluid exposure relies on a strong enough chlorine level to reliably inactivate pathogens. Household bleach (sodium hypochlorite) works when diluted to a concentration that can kill bacteria and viruses, even in the presence of organic matter. Among the given options, the mix with about 1 1/3 cups of bleach per gallon of water provides a relatively strong dilution—stronger than the other two or three mixes—making it the most effective for disinfection. The other options are far more dilute and would not reliably disinfect contaminated surfaces. For best results, use a fresh solution, allow adequate contact time, clean up any solids first, wear appropriate protection, and avoid mixing bleach with ammonia or acids.
