Prokaryotic flagella has :-Multifibrillar structure9 + 2 type pattern of monomersProtein coat on outside and hollow structureProtein coat on outside and solid structure

Prokaryotic flagella have a multifibrillar structure. They do not have a 9 + 2 type pattern of monomers, which is a characteristic of eukaryotic flagella. Instead, prokaryotic flagella are composed of a single type of protein called flagellin.

The flagellin proteins are arranged in a helical manner to form a hollow tube. So, they do not have a solid structure. The outside of the flagella is not coated with protein. Instead, it is covered by a sheath that is an extension of the cell membrane.

Therefore, the correct answer is: Prokaryotic flagella have a multifibrillar structure and a protein coat on the outside with a hollow structure.
