Which is used as a dry lubricant in machines running at high temperature is :-
Options:
Answer:
B

Graphite is an excellent dry lubricant, especially at high temperatures, due to its layered structure. The weak van der Waals forces between its hexagonal carbon layers allow them to slide past each other easily, reducing friction. This property makes it ideal for machines where liquid lubricants would degrade.
