The correct option is B 20
The shaft of cilia and flagella consists of an external sheath, semi fluid matrix and an axoneme. Axoneme has 9+2 fibrillar arrangement, comprising of nine peripheral doublet fibrils and two central singlet fibrils, central sheath, linkers and spokes. The 9+2 fibrillar arrangement means that there are a total of 20 microtubules.
