'Tribute' means -

The correct meaning of "tribute" is "an act to show respect."

A tribute is an expression of gratitude, respect, or admiration, often given to someone for their achievements or contributions. It can take various forms, such as speeches, ceremonies, or gifts, to honor someone.

For example:

• "The ceremony was a tribute to the heroism of the firefighters."

The other options:

• "To cause or to stimulate" refers to something more related to motivation or action.
• "To refuse to obey" doesn't align with the meaning of "tribute."
• "Climax" refers to the highest point of something, but is unrelated to the concept of a tribute.
