Answer:
The correct option is 3.
Step-by-step explanation:
The given inequality is
[tex]3x<3[/tex]
To solve the inequality, we have to isolate the variable x.
Divide both sides by 3 to solve the given inequality.
[tex]\frac{3x}{3}<\frac{3}{3}[/tex]
[tex]x<1[/tex]
The value of x is less than 1. So, the solution set of the given inequality is
{x | x < 1}
Therefore the correct option is 3.
