C). Neither twin could die because they were immortal gods.
Explanation:
As per the details given in the excerpt, the most logical and reasonable claim would be that 'neither of the twins could die as they were perpetual gods.' This deduction can be substantiated through the details like <em>'died, but didn't die', '...still lives and reigns'</em> while the details like '<em>...lives in the Sky-World', 'content with the world..he helped to create..the world of men', 'rule the affairs of men'</em>, etc. suggest that they were immortal gods. Thus, these details not only support the above inference but forms the base of the conclusion. Hence, <u>option C</u> is the correct answer.
