Answer 2

Bacteria have undefined nucleus.

Detailed Discussion:

• Here, the term "undefined" means that the sharply observable nucleus is not present within the cell.

• Bacteria being prokaryotic organisms don't have membrane bound cell organelles, similarly they don't have proper membrane bound nucleus.

• Instead, they have a loosely defined genetic material floating in the cytoplasm of the cell known as NUCLEOID.

_________________

• All the other options (like Yeasts, Plants and Animals) are eukaryotic organisms and hence have a proper membrane bound cell organelle and nucleus.
