Final answer:
The statement is true; a consistent system of linear equations has at least one solution, which can be a unique solution or infinitely many if the equations are dependent. The correct option is C.
Step-by-step explanation:
The statement "A consistent system of linear equations has one or more solutions" is true. Choice C is the correct answer.
This means that for a system to be considered consistent, it must either have a single unique solution or an infinite number of solutions if the equations are dependent (the same line or coincide). If we have two non-parallel lines intersecting, they meet at one point, which is the unique solution.
If we have two equations representing the same line, then there are an infinite number of solutions, as any point on the line is a solution.
