We are given the following inequality
[tex]4x\ne12[/tex]Let's first consider and solve the equation
[tex]4x=12[/tex][tex]x=\frac{12}{4}[/tex][tex]x=3[/tex]This means, for our inequality, x cannot be equal to 3, for if it were equal to 3 the inequality would be false.
Option C. is the correct answer.
