Which of the following is an example of Class 2 knots?

Class 2 knots are typically characterized by their ability to create a fixed loop at the end of a rope that can be tied and untied easily, yet secures well under load. The 'around the object bowline' serves this purpose effectively. It is designed to form a stable loop that doesn't slip, making it ideal for situations requiring a secure fastening around an object.

The structure of a bowline provides a fixed loop that maintains its shape and size even when manipulated or under tension. This feature is particularly useful in various applications, such as climbing, sailing, or rescue operations, where safety and reliability are paramount. The bowline also allows for easy untying after use, even after it has been loaded.

In contrast, the other knots listed do not fit the criteria for Class 2 knots in the same manner. The figure 8 loop, while commonly used for creating a loop, may not be as easily untied after being under tension. The water tape is not a recognized knot in this context, and the end of the line prussic is typically used for ascending and does not serve the same function of securing a fixed, easily untieable loop around an object. Therefore, the around the object bowline stands out as
