When a point is reflected across the x-axis, the x-coordinate remains the same while the y-coordinate changes its sign.
For the point (-3, -1):
- The x-coordinate is -3, which stays the same.
- The y-coordinate is -1, which becomes +1 when reflected.
Thus, the resulting coordinates after reflection across the x-axis are (-3, 1).
Therefore, the correct answer is:
B (-3, 1)
