Answer

Answer:

C. extremely rapid cooling

Brief Explanation:

When magma cools extremely rapidly, there is not enough time for large - scale crystal formation. Instead, the atoms or molecules are frozen in place in a disordered state, resulting in a glassy igneous rock. Slow cooling allows for large crystals to form, and the presence of oxygen or partial - melt cooling are not the main factors for glassy rock formation.
