High-hazard waste may contain

APathogens ✓ Correct

BRadioactive waste

CNon-reactive material

DCorrosive material

Correct answer: (A) Pathogens

Explanation

High-hazard waste may contain pathogens, the disease-causing microbes that make it dangerous to health.

Radioactive waste forms a separate hazardous category governed by its own rules.

Non-reactive material is inert and does not make waste high-hazard.

Corrosive material is hazardous but is classed by its chemical action rather than infectivity.

Infectious sharps and clinical residues are typical pathogen-bearing high-hazard waste.

Such waste needs sterilisation or incineration before disposal.
