The correct characterization of fungi is found in the choice that indicates they are multi-cellular organisms with nuclei. Fungi are indeed eukaryotic organisms, meaning they possess a defined nucleus within their cells, as well as other membrane-bound organelles.

Fungi can exist in both multicellular forms, such as mushrooms and molds, and unicellular forms like yeast. One of the defining characteristics of fungi is their ability to absorb nutrients from their environment through external digestion, which sets them apart from plants, since they do not perform photosynthesis.

In this context, although some fungi can be unicellular, not all fungi are characterized that way, as many are complex multicellular organisms with intricate structures. The choice referring to fungi as photosynthetic eukaryotes describes a different kingdom entirely—plants—because fungi do not contain chlorophyll and do not engage in photosynthesis. Also, fungi are distinct from prokaryotic organisms, which lack a membrane-bound nucleus, categorically placing fungi firmly within the eukaryotic domain.
