In order to remove side error from a sextant, you should adjust the _______________.
AI Explanation
The correct answer is C) Horizon glass to make it perpendicular to the sextant frame.
To remove side error from a sextant, the horizon glass must be adjusted to be perpendicular to the sextant frame. This ensures that the index mirror and the horizon mirror are parallel, which is necessary for accurate celestial observations.
The other options are incorrect because adjusting the telescope (A) or the horizon glass in relation to the index mirror (D) do not address the issue of side error. Adjusting the horizon glass to be parallel to the horizon mirror (B) also does not correct side error.
