Correct option is A
Accuracy refers to how
close a measured value is to the actual (true) value of a quantity. In measurement and manufacturing, a highly
accurate instrument or process ensures that the measured values
closely match the actual value, reducing deviation.
For example:
· If a
weighing scale shows 99.9 kg for a 100 kg standard weight, it is considered
highly accurate.
· If a
thermometer reads 37°C for a person with an actual body temperature of 37°C, it is
accurate.
