Which of the following statements about error guessing is true?

• A.Error guessing is a system that adopts artificial intelligence to predict whether software components are likely to contain defects or not
• B.Experienced testers, when applying error guessing, rely on the use of a high-level list of what needs to be tested as a guide to find defects
• C.Error guessing refers to the ability of a system or component to continue normal operation despite the presence of erroneous inputs
• D.Experienced testers, when applying error guessing technique, can anticipate where errors, defects and failures have occurred and target their tests at those issues
