Answer:

None

Step-by-step explanation:

Given the inequality


4>2-4x

First, we subtract 2 from both sides


\begin{gathered} 4-2>2-2-4x \\ 2>-4x \end{gathered}

Next, we divide both sides by -4.


\begin{gathered} (2)/(-4)>(-4x)/(-4) \\ -(1)/(2)-(1)/(2) \end{gathered}

Note: When you divide by a negative number in an inequality, the sign reverses.

Therefore, none of the options are solutions to the inequality.
