質問 6：
Consider the following examples of risks identified in different software development projects:
[I]. The contrast color ratio for both normal text and large text of a website does not comply with the applicable accessibility guidelines, making it difficult for many users to read the content on the pages
[II]. A development vendor fails to deliver their software system on time, causing significant delays to system integration testing activities that have been planned as part of a development project for a system of systems
[III]. People in the test team do not have sufficient skills to automate tests at the test levels required by the test automation strategy which does not allow production of an effective regression test suite
[IV]. In a web application, data from untrusted sources is not subject to proper input validation, making the application vulnerable to several security attacks Which of the following statements is true?
A. [II], [III] and [IV] are product risks; [I] is a project risk
B. [I] and [IV] are product risks. [II] and [III] are project risks
C. [IV] is a product risk; [I]. [II] and [III] are project risks
D. [I] and [III] are product risks; [II] and [IV] are project risks
