Both centrioles in a centrosome lie ..........(i)........ to each other and each of them contains ....(ii)..... peripheral fibril so ........(iii)......... array is present.

Step-by-step solution

Centrosome consists of two centrioles which lies perpendicular to each other and a pair of centriole is called as diplosome. Each centriole consists of nine peripheral fibril and a central protein hub. It thus shows 9 + 0 arrangement.
