The code oxy in the bottom white quadrant of a label conforming to nfpa 704 indicates that: a. the material can easily release oxygen to create or worsen a fire or explosion hazard b. the material will explode on contact with air c. the material reacts with water d. the material is radioactive

A.The material can easily release oxygen to create or worsen a fire or explosion hazard

Explanation:

The NFPA (National Fire Protection Association) diamond, is divided in four colors. The bottom quadrant of the white color symbol, and identify different types of special hazards.

In particular, OX refers to a solid or liquid chemical oxidizing agent that oxidize or accept electrons from other chemical compounds (such as combustible/burnable materials) by redox reactions. These materials also can readily give off oxygen or other oxidizing substances (such as bromine, chlorine, or fluorine). For this reason, the oxygen combined to other materials may increase the chance of an accidental fire or explosion.

Some examples of these compounds are: H₂O₂, KMnO₄, K₂CrO₇, NH₄ClO₄.

Option B

Explanation:

The NFPA is the national fire protection association which is divided into four colors. The OX here refers to the liquid or solid chemical oxidizing agent that has the ability to accept electrons from other chemical compounds.

The material inside the container can release oxygen and form harmful substances which can harm the nature and organism around container.

Hence, the correct answer is option B
