Which of the following is NOT a common bacterial shape?

Explanation:
Bacteria are often described by their basic cell shapes: spherical forms called cocci, rod-shaped forms called bacilli, and spiral forms called spirilla or spirillum. These terms describe how the bacterial cells look under a microscope and are standard ways scientists categorize bacterial morphology. Fungus, by contrast, is a different kind of organism entirely—fungi are eukaryotic and not bacteria—so it doesn’t correspond to a bacterial shape. That’s why it isn’t considered a common bacterial form. The other options—coccus, rod, and spirillum—are established bacterial shapes.
