Answer:
A. Actin filaments and microtubules
B. intermediate filaments
Explanation:
Actin filaments and microtubules are two major building blocks that form part of the cytoskeleton in all eukaryotic cells. Both actin filaments and microtubules play a fundamental role in the dynamics of the cytoskeleton, and they are involved in many essential cellular processes including, among others, mitosis, cytokinesis, intracellular transport, cell signaling, etc. Moreover, intermediate filaments are very stable structures found in animal cells, where they extend from a ring around the cell nucleus to the plasma membrane in order to provide consistency and shape to the nuclear envelope.
