Final answer:
The three naturally occurring elements manufactured during the Big Bang are hydrogen, helium, and lithium, which correspond to option C of the student's question.
Step-by-step explanation:
The elements that were produced in the Big Bang are hydrogen, helium, and lithium. The majority of the universe's matter consisted of about 75% hydrogen and about 25% helium after the Big Bang. Aside from these, only tiny amounts of lithium were produced. No heavier elements like carbon, oxygen, calcium, or iron were produced at the beginning of the universe; they were formed later inside stars through nuclear fusion processes.
Therefore, the answer to the student's question is C. Hydrogen, Helium, and Lithium.
