Warning Properties are defined as:

Warning Properties are defined as:

• A. The color and odor of a chemical
• B. The rate of a chemical's degradation
• C. Chemical characteristics that a person can use their senses to detect (odor, eye or respiratory irritation)
• D. The pollutant's regulatory classification

Answer: (C)

Warning properties are the chemical characteristics that a person can detect with their senses, such as odor or eye or respiratory irritation. This describes the perceptible cues that can alert someone to a hazard, rather than relying on how a chemical looks or how fast it degrades, or on formal regulatory classifications. Some substances have noticeable senses-based signals (strong odor or irritation), while others are odorless or colorless, yet still hazardous, which is why the sense-detectable aspect is the defining idea here.
