Solution

The correct option is B Microtubules
Cilia and flagella are the extended parts of the cell and act like locomotory appendages. The motion of cilia and flagella is created by the microtubules sliding past one another. This requires motor molecules of dynein, which link adjacent microtubules together and ATP.
Hence the correct option is A.
