Does carbon monoxide have a smell that resembles rotten eggs?

1. True

2. False

The correct answer is: False

While the smell of rotten eggs, or hydrogen sulfide, is often associated with gas leaks, carbon monoxide does not have a distinct odor. In fact, carbon monoxide is odorless, colorless, and tasteless, making it difficult to detect without a carbon monoxide detector. Choosing option B is the best answer as it accurately states that carbon monoxide does not have a smell that resembles rotten eggs. Option A is incorrect as it suggests that carbon monoxide does have a similar smell. It's important to note that carbon monoxide should not be relied on as the only indicator of a gas leak, as other gases may also be present with different odors.
