The correct answer is: Systematic.Systematic errors are errors that occur in experimental work due to flaws in the experimental design or equipment. These errors are consistent and repeatable, affecting the accuracy of the measurements. They can be caused by factors such as calibration errors, instrument drift, or experimental bias. Systematic errors can be identified and corrected by analyzing the data and adjusting the experimental setup accordingly.
