Final answer:

Step-by-step explanation:
The main point from the author's view, as gathered from the context provided, seems to dwell on the intersection of humanity with spirituality and destiny. Considering the various perspectives laid out, the most fitting answer appears to be that man's soul and spirit are immortal. This is seen in discussions of dualism, the transcendent nature of the soul, and religious beliefs in an unending, spiritual element of humanity. The suggestion is that despite physical constraints or boundaries, there is something about humans that transcends the material and is untouched by temporal power structures or environmental limitations.
Emphasis is placed on the spiritual substance of the soul and its eternal qualities, rather than on humanity's destiny or the balance of power defined by the nuclear arsenal. The viewpoints presented include a mix of religious and philosophical perspectives that highlight an immortal aspect of mankind, possibly as a counterpoint to the materialistic or deterministic views that devalue or negate the spiritual dimension of human existence. Therefore, option (C) is correct.
