Right.

To determine which word best completes the sentence, we need to understand the context and meaning of each option. Here's what each word means:

1. Beacon - a light or signal that guides or warns
2. Celestial - relating to the sky or the heavens
3. Detract - to diminish the importance or value of something
4. Precaution - an action taken to prevent something unwanted from happening
5. Retaliate - to respond to an attack or criticism with a similar action
6. Sham - something that is fraudulently presented as genuine
7. Uncouth - lacking good manners or refinement
8. Wholesome - conducive to physical or moral well-being; nourishing
9. Wistful - having or showing a feeling of longing or regret

Based on the meaning of each word, the best option to complete the sentence would be "wholesome." The other words do not convey the idea of something being a "development" that is good for the overall well-being or morality.
