A typical arthropod, such as an ant, has three body sections - head, thorax and abdomen.
However, the phylum "arthropoda" which literally translates to "jointed foot" (or, by extension, "jointed leg") includes more than a million species, some of which (the lobster, for instance) have as many as eight body sections, and others such as the arachnids (Spiders), only two.
For a basic science test, 3 is probably the answer.
