You may solve this problem in two ways:
If you solve the inequality explicitly (divide both sides by 4), you get
So, if has to be stricktly less than 4, you can only choose 1, 2 and 3 as answers.
Alternatively, you can plug in all of the values you're proposed and check if the inequality holds:
If , you have , which is true.
If , you have , which is true.
If , you have , which is true.
If , you have , which is false.
So, again, only 1, 2 and 3 are solutions.
