Helicobacter pylori is a flagellated spiral-shaped bacterium. Its spiral shape and flagella help it move through the mucus lining of the stomach, contributing to its pathogenicity. The other options are incorrect because they do not accurately describe both the flagellation and the spiral shape of H. pylori. Options describing it as rod-shaped or non-flagellated do not match its known scientific characteristics.

This option is incorrect. While flagellated, Helicobacter pylori is not rod-shaped; it is spiral-shaped.

This option is incorrect. Helicobacter pylori does not form chains; it is a single, spiral-shaped organism.

This is the correct option. Helicobacter pylori is a flagellated spiral-shaped bacterium, allowing it to move efficiently through the stomach's mucus lining.

This option is incorrect. While Helicobacter pylori is spiral-shaped, it is also flagellated, which aids in its motility.

This option is incorrect. Helicobacter pylori is both flagellated and spiral-shaped, not rod-shaped or non-flagellated.
