The correct answer is Talk to the captain, confess what you did, but emphasize that this is exactly why equipment checks are important.
Worst response: C
Competencies: Integrity (ethics), Interpersonal relations (teamwork)
Explanation: Following a dangerous incident, your teammate Tom is expected to be blamed for failing to spot a potential hazard in his inspection. Tom indeed should have found the error, but you are the one who caused it. You have a chance to either take responsibility for your part or to let Tom take all the blame. Notice that you are being asked about the worst response to the situation.
In response A, you wait. This seems like a passive response or a response that postpones your need to decide. However, deciding to wait is also a decision. Your first response is not to take responsibility. This is not a positive response, yet it is not the worst.
In response B, you take your share of the responsibility. You don't take the full blame, and indeed Tom has his part too. But you show solidarity and ethics. This is the best response.
Response C might be confusing. First, you confess to your part of the blame – you weren't focused enough while rolling the hose. You go on to emphasize why equipment inspections are important. While this is true, and they are indeed important, emphasizing it here seems to be an attempt to take the blame from you and turn it to Tom. You appear to be responsible, but in fact, you are trying to eat the cake and have it too – presenting yourself as ethical by confessing your part but also dodging the reprimand by pointing to someone else. This is the worst response.
In response D, you fail to confess your part in the incident and act insensitively to your teammate's situation. However, here you don't make things worse for him by trying to get your captain more upset with him. This is a negative response, but it is not the worst.
