In the prismatic compass A. the magnetic needle moves with the box B. the line of the sight does not move with the box C. the magnetic needle and graduated circle do not move with the box D. the graduated circle is fixed to the box and the magnetic needle always remains in the N-S direction

The correct answer is: C. the magnetic needle and graduated circle do not move with the box

The prismatic compass is a type of compass that uses a prism to magnify the image of the compass needle. The magnetic needle and graduated circle are fixed

The other options are incorrect because:

• Option A is incorrect because the magnetic needle does not move with the box.
• Option B is incorrect because the line of sight does move with the box.
• Option D is incorrect because the graduated circle is not fixed to the box.
