Choice A is the correct answer. Solve and find the minimum integer.

1. Subtract 2: $3x \geq 9$
2. Divide by 3: $x \geq 3$
3. Smallest integer: $x = 3$

💡 Strategic Tip: For $\geq$, the boundary value is included.

Choice B is incorrect because 4 is not the smallest. Choice C is incorrect because$2 < 3$ doesn't satisfy the inequality. Choice D is incorrect because 5 is not the smallest.
