Why is the calla lily not a true lily?

Explanation:
Understanding what defines a true lily hinges on flower structure and growth form. True lilies (genus Lilium) have an underground bulb for storage, and their flowers are made up of six petals/tepals and six stamens with filaments. The calla lily, despite its common name, isn’t a true lily because it uses a different floral arrangement—a spathe surrounding a spadix of tiny flowers—and it grows from a rhizome rather than a bulb. Because it lacks the key features of a bulb, six filaments, and six tepals, it isn’t classified as a true lily. The option that states it is missing a bulb, six filaments, and six tepals best reflects these structural differences.
