As pencil is slippery in touch and the graphite is also slippery in touch. Also, pencil is black in colour as graphite is.

Graphite is used in pencil because graphite gives blackness and softness to the pencil.

Graphite is a form of carbon and it is more reacted with the paper and it attached to it So, we can write smoothly.

Yes, graphite is the right answer because it allows all the carbon particles to arrange themselves in such a way that they form a parallel line to each other and allow the graphite to work smoothly like a lubricate. And also before they were using lead which was very poisonous and dangerous then they started using this graphite instead of the lead in the pencil "which is smooth, dark or black in colour.
