A homogeneous mixture is one that has a uniform appearance and composition all throughout. It can be solid, liquid or gas. In this case we can rule out the bowl of fruit, and the pack of mixed nuts since these both contain a variety of objects, rather than one single object. The bowl of salsa can also be ruled out, considering that salsa has many heterogeneous ingredients found inside of it.
Therefore, the best answer would be a slice of cheese.
Hope this helps!
