In this question, we are required to identify which of the listed options is not one of the large outer planets in the solar system. The outer planets, also known as gas giants (and including one ice giant), are Jupiter, Saturn, Uranus, and Neptune.

1. Understanding the Options:

   • Neptune: An outer planet and considered one of the larger planets.
   • Pluto: A dwarf planet, not classified among the large outer planets.
   • Saturn: A gas giant, one of the larger outer planets.
   • Uranus: An ice giant, also among the larger outer planets.

2. Analysis:

   • Among the options provided, both Neptune and Pluto represent different planetary classes. However, Pluto is not classified as a large planet at all, whereas the others are significant components of the outer planet classification.

3. Conclusion: The answer to the question is Pluto, as it is much smaller compared to Neptune, Saturn, and Uranus, making it the only option that does not fit the description of being large.
