Which knot in illustration D030DG below should be used to secure a line to a spar when the pull is parallel to the spar?

Correct Answer: Option C — P

A timber hitch is specifically designed for securing a line to a spar, log, or cylindrical object. When the pull is applied parallel to the spar, the friction of the turns causes the hitch to tighten securely around the object, preventing slippage during towing or lifting.
