**Core Concept**
Human anatomical waste is a biohazardous material that requires proper disposal to prevent the transmission of infectious diseases. This includes tissues and organs removed during surgery, autopsy, or other medical procedures.

**Why the Correct Answer is Right**
The correct disposal method for human anatomical waste is incineration. This process involves burning the waste at high temperatures (typically above 1000°C) to reduce it to a sterile ash, eliminating any potential pathogens. Incineration is a widely accepted and effective method for disposing of biohazardous materials, including anatomical waste. This method also reduces the volume of waste and prevents environmental contamination.

**Why Each Wrong Option is Incorrect**
**Option A:** Autoclaving is a method used to sterilize medical instruments and equipment, but it is not suitable for disposing of anatomical waste. Autoclaving involves high-pressure steam, which is not effective in destroying all pathogens in biohazardous materials.
**Option B:** Chemical disinfection is a method used to kill microorganisms, but it is not a recommended method for disposing of anatomical waste. Chemical disinfectants may not be effective against all pathogens, and the residues can be hazardous to the environment.
**Option C:** Landfilling is not an acceptable method for disposing of anatomical waste. Landfills can contaminate soil and groundwater, and anatomical waste can pose a risk to human health and the environment.

**Clinical Pearl / High-Yield Fact**
Incineration is the most effective method for disposing of human anatomical waste, reducing the risk of disease transmission and environmental contamination.

**Correct Answer: C. Landfilling is not an acceptable method for disposing of anatomical waste.
