Solution The correct option is D increase friction
Friction on a surface can be increased by increasing the roughness of the surface. When a matchstick is rubbed against the rough surface of the matchbox, a sparkle is produced. This is caused due to the large amount of friction produced between the surface of matchstick and matchbox.
