Solution

The correct option is A Spindle
Spindle fibres are made up of tubulin proteins which consist of 4 to 20 microtubules. Spindle fibers are formed from the ends or poles during cell division in animal cells. In animal cells, the spindle bears asters at the two poles. Such a spindle is called as amphiaster or centric spindle. In plant cells, the spindle is acentric or anastral.
