Explanation:

- Highlight (v.): To emphasize or bring attention to something. It's about making something stand out or more noticeable.

- Option 1 - Consider: To think about or reflect on something. This is not directly opposite to highlighting, as both can coexist.

- Option 2 - Describe: To give an account or representation of something. This involves detailing but not necessarily emphasizing. Not an antonym.

- Option 3 - Recognise: To identify or acknowledge something. Recognizing is about becoming aware, not highlighting or minimizing.

- Option 4 - Downplay: To make something seem less important or less significant. This is the opposite of highlighting, as it involves reducing emphasis.

Option 4 - Downplay is the correct antonym for highlight.
