A volcano with thick viscous lava would most likely have which eruption a - intrusive
b - explosive
c - metamorphic
d - gentle

B. Explosive eruptions

Explanation:

An eruption of highly viscous (very sticky) magma tends to produce steep-sided volcanoes with slopes that are about 30–35°.

Explosive eruptions generally involve magma that is more viscous and has a higher gas content. Such magma is often shattered into pyroclastic fragments by explosive gas expansion during an eruption. Volcanic eruptions may fall into six major types: Icelandic, Hawaiian, Strombolian, Vulcanian, Pelean, and Plinian.

the second type of galaxy is called a barred spiral, which has a thing called a bar straddling the nucleus
