I have been asked this question during an interview for a job.

Asked question is from Organelles in Eukaryotic and Prokaryotic Cells in portion Cell : The Unit of Life of Biology – Class 11

Answer 1

Correct choice is (b) Microtubules are composed of protein actin and microtubules are composed of protein tubulin

For explanation I would say: Cytoskeleton is the network of minute proteinaceous structure in the cytoplasm and which mainly contains microfilaments and micro tubules. Microtubules are composed of protein tubulin and microtubules are composed of protein actin.
