The correct option is C 95-97% tubulin and 3-5% RNA.
Spindle is astral (amphiastral) and arises from centriole in animal cell. It is anastral in plant cell and arise from cytoplasmic proteins by gelation. It consists of microtubules made up of sulphur rich tubulin protein (95-97%), RNA (3-5%) and ATPase. Spindle can be seen with polarizing microscope only.
So, the correct option is C.
