Solution
The correct option is D Random error
The most important features of random errors which usually occur are:
(1). Small errors tend to be more frequent than the large ones. So that they are the most probable.
(2). Positive and negative errors of the same size happen with equal frequency. That's why they are equally probable.
(3). Large errors occur infrequently and are impossible.
Hence, option (d) is the correct answer.
