Assertion : The arrangement of axonemal microtubules in cilia or flagella is called 9 + 2 array. Reason : The axoneme usually has nine pairs or doubles of radially arranged peripheral microtubules, and a pair of centrally located microtubules.

How many statements are incorrect about centrosome ? (i) Peripheral microtubules are arranged as triplet (ii) Centrioles are not self duplicating units (iii) Peripheral microtubules are linked to each other by radial spokes (iv) Central part does not have any microtubules
