The correct answer is - B. Rhyolitic.
The rhyolitic magma has a trademark signature to be the magma type that causes the most catastrophic, powerful, explosive volcanic eruptions. This is due to the composition of the magma. This type of magma is very high in silica content, which in turn makes it very viscous, and because it is very viscous, the high amount of gasses that it contains remain trapped in it, the pressure is building up inside of it, so when it reaches the surface it is highly explosive.

Alpha Centauri A (G2)
Sirius (A1)
Spica (B1)
Explanation:
The habitable zone, also known as the circumstellar habitable zone, is the range of distances from a star where it is not too hot and not too cold for liquid water to exist on the surface of surrounding planets.
The location of a star’s habitable zone is dependent upon its luminosity, which is the amount of light emitted by an object in a unit of time, because a star’s luminosity increases with time; and also the star's mass.
The inverse square law of light brightness can be used to determine the extent of the habitable zones for different luminosity stars with the formula:
star boundary = Sun boundary × squareroot[(star luminosity)/(Sun luminosity].
