Answer:

C

Explanation:

The red portion shows all numbers GREATER THAN or EQUAL TO 0.

So that would be x ≥ 0

Looking at the answer choices, there is no "x", rather "√x"

To make it "x", we need to square both sides and the option C wouldn't make a difference. Shown below:

$√(x) >0\\(√(x) )^2>0^2\\x>0$

Option C is right.
