Which statement best defines stylus? a writing tool that is pointed on one end and triangular at the other. a sculpture built using very large stones. a flat stone used for grinding paint. a band used in art to depict multiple events or scenes in a single work.

I would say it's a writing tool that is pointed on one end and triangular at the other.  But I'm not 100% sure.  Hope this helped!
