# Explanation:## Step1: Identify the nature of each example### Evaluate each example to determine if it is a homogeneous mixture or not. A homogeneous mixture has a uniform composition throughout.## Step2: Analyze each option### - **Option A:** The balloon contains helium atoms, which are uniform throughout. However, the statement claims they are not uniform, making it incorrect.- **Option B:** The oil and water mixture is not homogeneous because oil and water do not mix evenly; they form separate layers.- **Option C:** The bowl of cereal is not homogeneous because the cereal and milk are not uniformly distributed.- **Option D:** Air is a homogeneous mixture because it contains several gases (like nitrogen, oxygen, etc.) that are uniformly mixed.# Answer: ### D. Air, because it contains several gases, and they are uniform throughout
