Correct Answer:
B. The departure was sudden or planned but without a ready replacement.
Inference involves drawing conclusions based on the information provided, even if not explicitly stated. The key phrases in the sentence are "resignation was accepted with immediate effect" and "though no successor has been named."
- The phrase "immediate effect" suggests an abrupt departure, either due to an unforeseen event or a planned but expedited exit. The crucial part is "no successor has been named," which strongly implies that the company was not fully prepared for this transition. This combination leads to the inference that The departure was sudden or planned but without a ready replacement.
- The CEO was promoted is incorrect because the text states "resignation," which means leaving the position, not moving up.
- The company will close down cannot be inferred; a CEO's departure, even sudden, does not automatically lead to company closure.
- The successor will be the old CEO is illogical, as a resignation implies a permanent departure and the need for a *new* successor.
