Detailed Solution

All of the above statements are correct regarding precautions while taking measurements.
The precautions which should be taken care of while measuring with a ruler: -
●       The ruler should be close to the object.
●       The eye should be in front of the point of measurement.
●       Avoid measuring with a broken ruler.
To take the measurement of the length of an object, we must put the scale along its length without bending it. If the end of the scale is broken in such a way that we are not able to see the zero mark, in that case, we can subtract the mark from the reading at the other end. The position of the eye during measurement is important. During measurement, our eyes must be exactly in front of the point where the measurement is taken.
