At this time, the most commonly accepted hypothesis describing the origin of our solar system is called the  aDoppler hypothesis. bstellar hypothesis. csteady state hypothesis. dnebular hypothesis.

Which of the following is the most widely accepted explanation for the origin of our solar system? aThe big bang theory, which states that an infinitely small, infinitely dense particle exploded to create our solar system. bThe steady state theory, which states that all regions of the universe, including our solar system, have always existed in their current forms. cThe giant impact hypothesis, which states that the planets and other bodies in our solar system resulted from collisions between the sun and various large bodies. dThe nebular hypothesis, which states that gravity caused a small fragment of a huge, rotating cloud of space dust and gas to collapse, forming a large accretion disc that became the sun and planets.
