The logical fallacy used in above given sentence is <u>slippery slope</u>.
<u>Option: B</u>
<u>Explanation:</u>
A slippery slope argument is usually a negative claim where an effort is made to prevent others from following a plan of action as it could lead to a certain undesirable consequence when they do so. The effectiveness of such a statement relies on the warrant, i.e. whether a mechanism which leads to the significant result can be shown or not. Often this sort of argument is used as a means of fear-mongering, where the possible effects of a given action are manipulated in an effort to intimidate the public.
