Which bend or knot is used to tie a small line to a larger one?

The becket bend is the correct choice for tying a small line to a larger one due to its design and functionality. This knot is especially effective in creating a secure connection between two lines of differing sizes. The becket bend provides a strong hold without slipping, which is crucial when working with varying diameters of rope or line, such as when securing a smaller rope to a larger mooring line. It is commonly used in boating and marine applications where reliable knots are essential for safety and stability.

The other knots, while useful in specific situations, do not serve the same purpose as the becket bend. The bowline creates a fixed loop at the end of a line, which is useful for towing or securing items, but it is not designed for attaching different sized lines. The clove hitch is primarily a hitch for securing a line to a post or a pole, offering more flexibility than security between two lines. The lark's head knot, often used to attach a loop of rope to another object, also does not provide the same level of security when connecting different sized lines together.
