The given diagrammatic representation (Figure 8.10) shows the cross-section of a eukaryotic flagellum/cilium. Which statement correctly identifies the components and microtubular geometry of this axoneme?

1. It possesses 9 peripheral single microtubules and 2 central triplets enclosed in amorphous pericentriolar satellite material.
2. It exhibits a \( 9+0 \) pattern where nine triplets are directly fused to the plasma membrane without any radial spokes.
3. It consists of 18 radial spokes connected directly to the outer plasma membrane without forming interdoublet bridges.
4. It possesses an axoneme with nine doublets of radially arranged peripheral microtubules and a pair of centrally located microtubules (\( 9+2 \) array) enclosed by a central sheath.
