In order to remove the error of parallax when taking measurements with a metre rule, the eye should be focused

The correct answer is:

**C. vertically downwards on the markings**

Focusing vertically downwards ensures that your line of sight is perpendicular to the scale of the metre rule, minimizing parallax error. Parallax error occurs when the observer's eye is not directly in line with the measurement markings, causing the reading to appear displaced.
