Solution
The correct option is D 140.8 cm
To increase accuracy we can take multiple measurements and calculate the average of the recorded measurements.
The recorded measurements here are 40.0 cm, 141.5 cm and 141.0 cm.
So, the average will be = (140.0 + 141.5 + 141.0)/3 = 140.8 cm.
Hence, among the given options the most accurate value will be 140.8 cm
