Question 2318 Deck General

The correct answer is C) human error. The majority of minor oil spills are caused by human error, such as mistakes during routine operations, improper handling procedures, or lack of proper training and oversight. This is in accordance with regulations and guidelines set forth by the US Coast Guard and other regulatory bodies, which emphasize the importance of proper training, procedures, and oversight to prevent oil spills and other maritime accidents. The other options are less likely to be the primary cause of most minor oil spills. Major casualties (A) are rare events, unforeseeable circumstances (B) are uncommon, and equipment failure (D) is typically less frequent than human error as the root cause of minor spills.
