The right answer is balls (globules).

Microtubules are constituent fibers of the cytoskeleton, as are actin microfilaments and intermediate filaments.

The microtubules are formed of tubulin dimers (which have a spherical shape) each consisting of two subunits, tubulin α and tubulin β, linked by non-covalent bonds.

Actin, the main component of microfilaments, is a bi-globular protein that plays an important role in architecture and cell movement. It is present in all the cells of the body (ubiquitous protein), and especially in the muscular cells.
