The one-sample runs test can be applied to both sequential and non-sequential observations. Therefore, statement C is not true. A is true, as the test is also called the Wald-Wolfowitz test. B is true, as the purpose of the test is to detect nonrandomness. D is partially true, as the test may identify a lack of independence in the data, but it is not exactly the same as a test for autocorrelation.
