One of the following readings represents the measurement of the measurement of the length of a metal rod using vernier callipers. Taking the reading accuracy into consideration, the most likely one is 

Answer Details

The most likely reading for the length of a metal rod using vernier callipers would be 5.160cm. This is because vernier callipers usually have a scale with increments of 0.1mm, and 5.160cm is the closest reading to 5.16cm, which would be the smallest increment that can be accurately measured using vernier callipers.
The other options, 5.165cm and 5.0cm, may not be as accurate as they do not match up with the smallest increment that can be measured using vernier callipers.
