Answer is Wrong!
Answer is Right!
The correct answer is D. all of the above.
Systematic errors are errors that are always in the same direction and can be caused by a number of factors, including instrumental errors, environmental errors, and observational errors.
Instrumental errors are errors that are caused by the instrument being used to make the measurement. For example, if a thermometer is not calibrated correctly, it will give inaccurate readings.
Environmental errors are errors that are caused by the environment in which the measurement is being made. For example, if a measurement is being made in a windy environment, the wind can cause the measurement to be inaccurate.
