d

b. Hydrogen
Hydrogen is the most abundant element in the Universe. This is because the Universe began with the Big Bang, during which hydrogen was created in large quantities. Hydrogen is also constantly being formed in stars through the process of nuclear fusion, where hydrogen atoms combine to form helium.
Furthermore, hydrogen is the primary fuel for stars, including our Sun. Stars undergo nuclear fusion reactions that release vast amounts of energy, and they convert hydrogen into helium in this process. This continuous cycle of hydrogen being created and consumed in stars contributes to its abundance in the Universe.
Hydrogen is also present in vast amounts in interstellar clouds, which are the birthplaces of new stars. These clouds contain large amounts of hydrogen gas, as well as other elements and compounds, that eventually condense and collapse under gravity to form new stars and planetary systems.
In summary, hydrogen is the most abundant element in the Universe due to its primordial production during the Big Bang and its continuous creation and consumption in stars through nuclear fusion.
