A. (2, 1)
When a point is reflected along the x-axis, the x-coordinate stays the same while the y-coordinate is multiplied by -1 (its sign is changed). This means that for the point (2, -1), reflecting across the x-axis will invert the sign of the y-coordinate from -1 to 1, while the x-coordinate remains unchanged. Therefore, the new reflected point becomes (2, 1).
