Statements A, B and D correctly identify key features of robust online examination systems, such as automatic scoring, security tools and randomised question papers. Statement C is false because many online systems allow descriptive answers that are later evaluated by human examiners. ICT expands options for both objective and subjective assessment rather than restricting them. Hence, the correct combination is A, B and D only.
Option A:
Option A is correct because it groups the three statements that align with current practice in online testing. It highlights automation, security and randomisation without denying the possibility of human marking. By excluding C, it avoids an overly restrictive view of online exams.
Option B:
Option B is incorrect because it includes only A and D and omits B. Statement B is also correct, since secure browsers and proctoring are widely used to curb malpractice. Leaving out B underplays the importance of security in online examinations.
Option C:
Option C is incorrect because it groups B and C as correct statements. While B is true, C is false because subjective questions can be collected online and marked manually. Including C makes the combination invalid.
Option D:
Option D is incorrect because it treats all four statements as correct, thereby accepting C. Since C misrepresents the capabilities of online systems, any option containing it cannot be correct.
