41) Which non-metal is used for manufacture of pencil lead

Solution
Graphite is used in the manufacture of pencil lead because it imparts an impression on paper when used, which other materials are unable to do so.
Graphite is an allotrope of carbon and it is highly soft textured (because graphite has a layered structure and the layers can slip past each other, hence can be cut easily) and lustrous.
