Answer:
b) Appeal to ignorance, present in an argument in which the arguer relies on the supposition that, due to a lack of conclusive evidence, the conclusion of an argument should be accepted.
Explanation:
The logical fallacy of appeal to ignorance is when an argument's conclusion is based on the absence of any evidence proving against it. In other words, an appeal to ignorance is when an arguer relies on the supposition that the lack of any evidence proving otherwise makes his conclusion acceptable and right.
In the given case of the existence of aliens, the speaker decides that <em>"[since] no one has yet been able to [prove that aliens exist]", </em>therefore, it must be true and accepted that <em>"aliens do not exist."</em> This argument follows the logical fallacy of an appeal to ignorance.
Thus, the correct answer is option b.
