Introduction / Context:This question tests complement requirements after verbs like “require.” The sentence is split into parts; pick the segment with the error. Given Data / Assumptions: “Require” followed by “to” must take a bare infinitive verb (e.g., “to attend”). The sentence describes an ongoing course. Concept / Approach:“Is required to” is incomplete without a following verb. It needs an infinitival complement such as “undergo,” “attend,” or “complete.” Step-by-Step Solution: A: “He has been undergoing” — correct present perfect progressive.B: “the special training course” — correct noun phrase.C: “which each of the employees” — correct relative-clause beginning; number agreement okay (“each … is”).D: “is required to.” — erroneous because it lacks the infinitive verb; should be “is required to undergo” or “is required to attend.” Verification / Alternative check: Corrected version: “He has been undergoing the special training course which each of the employees is required to undergo.” Why Other Options Are Wrong: A, B, and C are structurally fine; only D is incomplete. Common Pitfalls: Stopping a “to”-infinitive after “required” without the main verb. Final Answer:is required to.
