Answer:
<h2>C. two intersecting lines</h2>
Step-by-step explanation:
When we study system of equations, we find out that they can be classified in different ways, if they have a unique solution or if they have infinitely many solutions, or if they don't have any solutions at all.
In this case, a system of linear equations that have only one solution, means that those equations represents intersecting lines, and as you can already know, lines can meet at one unique point.
Therefore, the right answer is C, two intersecting lines have one unique solution, because lines cannot intersect in more than one point at the time.
