Show answer & explanation

Correct answer: A

Concept

Hazardous waste is classified by the property that makes it harmful: toxicity, reactivity, corrosivity, or infectious potential.

Match each example to its defining hazard. Pesticides may be toxic, nitroglycerine is unstable and reactive, acids corrode materials, and used hypodermic needles can carry pathogens.

Application

Waste type

Example

Why it fits

Toxic waste

Pesticide

Toxic pesticides can poison living organisms through exposure.

Reactive waste

Nitroglycerine

Nitroglycerine is unstable and can react or explode when disturbed.

Corrosive waste

Acid

Acids can corrode materials and damage tissue.

Infectious waste

Hypodermic needle

Used hypodermic needles can be contaminated with disease-causing microorganisms.

Cross-check

  • Pesticide represents toxicity more directly than corrosivity in this classification.

  • Nitroglycerine represents reactivity because instability is its defining hazard.

  • Acid represents corrosivity because it attacks materials and tissue.

  • A used hypodermic needle represents infectious waste because it can transmit pathogens.

Result

Therefore, the matching is A-IV, B-III, C-I, D-II.
