Answer 1

"Fallacies, which rely on faulty logic, can make an appeal to logos less effective" would be the best option since telling untruths of any kind, regardless of intent, almost always undermine the argument you wish you make. 

Answer 2

The correct answer is B. Fallacies, which rely on faulty logic, can make an appeal to logos less effective

Explanation:

Logos refers to a mode of persuasion that uses logic to persuade or convince people about some point, this means the speaker uses arguments based on logic to show his point. On the other hand, fallacies are invalid arguments that seem to be the truth as fallacies imply wrong reasoning (use of logic) that leads to arguments that do not support a point, contain ideas that are not really connected or are misleading. Considering this, as fallacies use logic in an inappropriate way to create arguments, fallacies make logos, which is the use of logic, less effective. This can be explained as fallacies show using logic does not guarantee an argument is valid and thus it shows using logic might not be the best way to persuade in all cases.
