Explanation:

- Dissolve: It means to mix with a liquid and become part of it, or to end or disappear.

- Emerge: This means to come out or become visible. It implies appearance rather than disappearance.

- Consolidate: This refers to making something stronger or more solid, which is opposite to dissolution.

- Fade: To gradually disappear or lose brightness or color.

- This is the correct synonym for "dissolve" in the sense of something disappearing or vanishing.

- Repair: To fix or mend something, which is not related to disappearances or liquid mixing.
