In the following question, an incomplete statement followed by fillers is given. Pick out the best filler to complete the incomplete statement, correctly and meaningfully. Her decision-making is so inconsistent that she __________.

Explanation: The phrase "Her decision-making is so inconsistent" implies unpredictability or frequent changes in decisions. The best option is (B), as it logically follows that an inconsistent decision-maker would often be unsure about their next step. Option (1) contradicts the idea of inconsistency because following a strict routine implies stability. Option (3) also contradicts the idea of inconsistency, as it suggests unwavering decisions. Option (4) may seem related, but it focuses more on responsibility rather than inconsistency. Thus, (2) is the most appropriate choice, maintaining logical coherence with the given statement.
