Correct answer · Option 4
A-IV, B-II, C-I, D-III
Explanation
The axoneme has 9 peripheral doublets and 2 central microtubules (9+2). Centrioles have 9 peripheral triplets of tubulin without central microtubules (9+0). Hub is the central proteinaceous part of the centriole, and radial spokes connect peripheral doublets to the central sheath.
