Which is a homogeneous mixture? A air B pizza C jar of mixed nuts D salad dressing

A) Air

Explanation:

A homogenous mixture is one that has uniform composition throughout. Air is comprised of several types of molecules (oxygen, carbon, nitrogen ...). If you take a chunk of air, you will get the same ratio of those molecules if you take a different chunk of it. They will be made of the exact same things no matter where you take your sample.
