Final answer:

It is false that all hazardous materials can be detected by smell, as some, like carbon monoxide, are odorless and tasteless.

Step-by-step explanation:

The presence of hazardous materials cannot always be detected by the sense of smell; the statement is False. Certain hazardous materials, such as carbon monoxide, are odorless and tasteless, making them undetectable to human senses until potentially harmful exposure has occurred.

Contrastingly, substances like ammonia and natural gas have distinct odors added to them to ensure that leaks can be detected by smell.

No, the presence of hazardous materials cannot always be detected by the sense of smell. Some hazardous materials, like carbon monoxide, are odorless and tasteless.

For example, carbon monoxide is a dangerous gas that is produced by burning fuels such as gas, oil, coal, and wood. It is colorless, odorless, and tasteless, which makes it impossible to detect through the sense of smell. Therefore, the correct answer is B. False.
