Show answer and explanation

Correct answer: (A) Waste should go to a common biomedical-waste facility except rural areas where one is unavailable.

Explanation

The official answer is **A**. Common treatment facilities are the intended destination where available; B incorrectly prohibits authorized transport. C assigns anatomical/soiled waste to red rather than yellow segregation and an inappropriate general treatment route. For the referenced gravity-flow autoclave conditions, the listed minimum times at 121°C and 149°C are 60 and 30 minutes, a reduction of 30 rather than 15,so D is false. A is simplified examination wording: actual facility-availability obligations are more specific than a blanket rural exception.
