The kingdom that includes eukaryotic, multicellular organisms that reproduce sexually and possess complex organ systems is indeed Animalia. Organisms in this kingdom are characterized by their ability to move, consume organic material for energy, and develop from embryos. They have specialized tissues and organs that perform various functions, enabling intricate behaviors and interactions with their environment.

While fungi are also eukaryotic and can be multicellular, they primarily reproduce through spores and do not have complex organ systems like those found in animals. Bacteria, on the other hand, are prokaryotic and unicellular, lacking the complexity associated with multicellular eukaryotic organisms. Protista is a diverse kingdom that includes both unicellular and simple multicellular organisms, but it does not have the same level of complexity and specialization as the Animalia kingdom.

Thus, the characteristics of sexual reproduction and complex organ systems align specifically with the Animalia kingdom.
