Which of the following is NOT a form of compound flower?

Explanation:
Inflorescences can be simple or compound. A Corymb forms a flat-topped cluster because the individual flowers arise along a single axis with pedicels of different lengths, but there are no secondary branches. That makes it a simple inflorescence rather than a compound one. In contrast, an umbel can become compound when its rays bear subumbels, a raceme can develop into a branched panicle (a compound raceme), and a spike can participate in more complex, branching arrangements in some species. So the flat, level-headed arrangement of a Corymb is the form that isn’t a compound inflorescence.
