Final answer:
Victor focused on the elixir of life because it promised eternal youth and knowledge. The correct answer is B).
Step-by-step explanation:
The reason Victor focused on the elixir of life rather than the philosopher's stone was because the elixir offered the promise of eternal youth and knowledge, as mentioned in the passage. Victor believed that by creating the elixir, he could prolong life for years, and possibly indefinitely, but he also acknowledged that it could have negative consequences and disrupt the natural order of things, causing people to curse it. Therefore, option b) The elixir of life promised eternal youth and knowledge is the correct answer.
