Which of the following characteristics is most useful when classifying a eukaryote Into a kingdom, the way the organisms feed, the organisms structure and form, they way the organisms moves

The most useful characteristic when classifying a eukaryote into a kingdom is the organism's structure and form. This is because the structure and form of an organism can provide more information about its evolutionary relationships, phylogenetic similarities, and anatomical features, which are often used to classify organisms into different kingdoms. The way an organism feeds and moves can vary greatly within a single kingdom, as different organisms within the same kingdom can have diverse feeding and movement strategies.
