Explanation:

- Retort: This word often means to reply in a quick, witty, or sharp manner, usually in response to a comment or criticism.

- Option 1 - Request: This means to ask for something. It doesn't fit well as a synonym for retort, as it lacks the quick reply element.

- Option 2 - Advise: This involves offering suggestions or recommendations, which is different from the concept of responding quickly.

- Option 3 - Reply: This is a direct response to a comment or question. It is the closest synonym to retort, as both involve replying, although retort implies a certain sharpness.

- Option 4 - Question: This involves asking, rather than replying or responding, so it's not suitable as a synonym.

Option 3 - Reply is indeed the most suitable synonym for retort. .
