The smoke rings exiting the chimney are an example of a Stream line.

Here's why:

1. Streamline: A streamline is a line that is everywhere tangent to the velocity field. In other words, a fluid particle moving along a streamline would follow the path of the streamline. In the case of the smoke rings, the smoke particles follow a specific path that is tangent to their velocity, forming the shape of the ring as they exit the chimney.

2. Streakline: A streakline is the path that a series of fluid particles take if they were continuously released from a single point. This doesn't apply to the smoke rings as they are not released from a single point continuously.

3. Pathline: A pathline is the actual path travelled by a given fluid particle. While the smoke particles do travel a path, they do not form the shape of the smoke ring due to their individual paths.

4. Streamtube: A streamtube consists of a bundle of streamlines. The smoke rings could be considered a streamtube if they were composed of multiple streamlines, but typically a smoke ring is formed from a single streamline.

Therefore, the smoke rings exiting the chimney are best described as an example of a streamline.
