Answer

Answer:

B. hardness and brittleness

Brief Explanations:

Ionic compounds like chalk are hard and brittle. Brittleness allows chalk to leave marks on the chalk - board as small pieces break off during writing. High melting point is not related to writing on a board, ionic compounds can dissolve in water, and chalk is usually white or light - colored, not multicolored.
