Statements A, C and D are correct, while B is the only wrong statement. A is correct because discussion forums are a standard tool for asynchronous interaction among dispersed learners. C is correct since short video lectures are commonly used to deliver core content in MOOCs. D is correct as peer assessment tasks create communication opportunities between learners. B is wrong because although feedback may be limited or automated, it is not impossible for learners in MOOCs to receive feedback on their work.
Option A:
Option A is incorrect because it labels A and B as wrong statements. A is actually true in describing the role of discussion forums in MOOCs. Even though B is wrong, grouping it with A makes this combination inaccurate.
Option B:
Option B is correct because it identifies B only as the wrong statement. B overgeneralises by claiming that feedback is impossible in MOOCs, ignoring mechanisms such as automated quizzes, peer review and occasional instructor feedback. By leaving A, C and D outside the wrong set, this option matches the actual pattern of correctness.
Option C:
Option C is incorrect because it groups B and C as wrong. C is actually correct in noting the extensive use of short video lectures in online courses. Including C in the wrong set therefore misrepresents the communication methods used in MOOCs.
Option D:
Option D is incorrect because it treats A, B and C as wrong. Both A and C are accurate descriptions of typical communication tools and content delivery modes in MOOCs. Combining them with the genuinely wrong B yields an overinclusive and inconsistent set of wrong statements.
