The graduations in prismatic compass i) are inverted ii) are upright iii) run clockwise having 0° at south iv) run clockwise having 0° at north The correct answer is A. (i) and (iii) B. (i) and (iv) C. (ii) and (iii) D. (ii) and (iv)

The correct answer is A. (i) and (iii).

The graduations in a prismatic compass are inverted, meaning that 0° is at south and 360° is at north. The graduations also run clockwise, which is the standard way for compasses to be oriented.

Option (ii) is incorrect because the graduations are inverted, not upright. Option (iii) is correct because the graduations run clockwise. Option (iv) is incorrect because 0° is at south, not north.
