Answer:
Option (B)
Explanation:
Felsic magma refers to those magma that are comprised of more than 65% of silica content and are highly made up lighter elements like oxygen, silicon, sodium, aluminum, potassium, and are light-colored in comparison to the basic magma. Due to its high silica content, these are high viscosity magma and flows at a much slower rate. The felsic magma crystallizes at a relatively low-temperature rocks and the rocks that are formed from this type of magma have a specific gravity of less than 3.
Thus, the correct answer is option (B).

Sorry for the first answer you received, that is incredibly inappropriate. I searched several resources and I’m pretty sure that your answer is D. 2 valence electrons.
Answer:
The number of energy levels increases as you move down a group as the number of electrons increases. Each subsequent energy level is further from the nucleus than the last. ... The outermost electrons are repelled by the inner shell electrons (Screening effect) and hence, the atomic size increases.
Explanation:Increase in atomic size
