When towing, the least amount of tension will be on each bridle leg when the two legs __________.

Correct Answer: Option A — form a small angle with each other

The tension in each leg of a bridle is inversely proportional to the angle between them. As the angle decreases, the vector force component along each leg is minimized. A narrow angle ensures that the majority of the towing force is directed forward, reducing unnecessary stress on the bridle components.
