Which protein is present in cilia and flagella?

$S$ - Statement: Basal bodies are associated with the formation of cilia and flagella.
$R$ - Reason: Nucleoli contain the nucleus and chromatin material.

Study the following statements on cilium or flagellum and answer the question.
$(i)$ Cilium / Flagellum contains an outer ring of nine doublet microtubules surrounding two singlet microtubules.
$(ii)$ Cilia are smaller which work like oars,causing the movement of either the cells or surrounding fluid.
$(iii)$ Flagella are comparatively longer and responsible for cell movement.
$(iv)$ Cilium and flagellum are covered with plasma membrane. Which of the above statements are correct?
