Detailed explanation-1: -The microtubules, which together produce cylindrical structures such as flagella and cilia, are arranged in a 9+2 pattern. The 9+2 configuration is made by 9 fused pairings of microtubules on the outside forming a cylinder and two unfused microtubules in the center of these 9 pairs.
Detailed explanation-2: -Here, nine doublet microtubules are arranged peripherally surrounding a central pair of singlet microtubules. But they differ in length, number per cell, and even the beating pattern. So, the correct answer is ‘Centrioles. ‘
Detailed explanation-3: -The 9 + 2 arrangement refers to how the microtubules are organised in structures such as the flagella and cilia. It has 9 pairs of microtubules situated on the outside that are bound together and 2 pairs of microtubules in the middle that are not bound together.
