Big Bang is the term that describes how the solar system was formed.
The term that best describes how the solar system was formed is "solar nebula theory." This theory suggests that the solar system originated from a rotating cloud of gas and dust, known as a solar nebula. Under the influence of gravity, this cloud collapsed, leading to the formation of the Sun at its center and the planets, moons, and other celestial bodies from the remaining material.
D. The sun. All planets in our solar system orbit the sun thus it is the best reference when describing the motion of the planets within that solar system.
The best view of the solar system is that from either of the two Voyager spacecraft which show the solar system from outside. The modern view of the solar system is that there are 8 planets orbiting the Sun. There are also a lot of smaller bodies orbiting the Sun. They are mainly the dwarf planets, asteroids, Kuiper Belt objects, and comets.
The answer to that is entirely your opinion.
I think you mean "protoplanet hypothesis". In fact, astronomers usually call it the Nebular Hypothesis A protoplanet is a planet-like object that hasn't fully developed into a planet. Why that hypothesis? It's because it is the best we have to describe the origin of the solar system according to the Laws of Physics.

Best guess; between 4.7 and 4.5 billion years ago.

Our solar system is located on one of the arms of the spiral, off to one side of the galaxy.
The best diagram to illustrate the stage in the formation of the solar system at which the Sun formed is the protoplanetary disk model. This model shows a rotating disk of gas and dust surrounding a central mass, where the Sun forms from the gravitational collapse of material in the core. As the central mass grows, nuclear fusion ignites, marking the emergence of the Sun while the surrounding material eventually coalesces into planets, moons, and other celestial bodies.
