Solution
The correct option is B Treadmilling
Treadmilling is a phenomenon observed in cytoskeletons like actin filaments and microtubules. In this, one end of the filaments grow while the other end of the filaments shrinks.
Due to this, it appears as if the filament is moving in the cytoplasm. It is the assembly and disassembly of the filament.
During treadmilling, the length of the filament remains constant as at one end assembly takes place and at another end, it dissociates.
