B Correct answer
Explanation

Graphite's layered structure with delocalized electrons between the carbon layers makes it an excellent conductor of electricity, which is the primary reason it's used in electrodes. While options A, C, and D describe some of graphite's properties (metallic luster, crystalline nature, corrosion resistance), these are not the main reasons for electrode use.
