A fine-grained igneous rock forms

Choice B is the right option since the cooling is fast.

The minerals may not have enough room to develop owing to a sudden cooling and therefore their structure is delicate and glassy. The composition of an igneous rock depends on how quickly the magma is cooled when the volcanic eruptions occur. Slow cooling allows big crystals to grow while rapid cooling allows tiny crystals to appear.
