Answer

Answer:

C. extremely rapid cooling

Brief Explanations:

When magma cools extremely rapidly, there is not enough time for large - scale crystal formation. Instead, the atoms or molecules lock into a disordered, glass - like structure, forming a "glassy" igneous rock. Slow cooling allows for crystal growth, cooling in oxygen doesn't directly cause glassy formation, and partial melt cooling is not related to glassy igneous rock formation in this context.
