The correct answer is "last three rows of the table".
To answer this question, we need to understand what the `race.tail()` function does. In the given context, `race` refers to the dataframe or table that contains the data for the 10 men in a 100-meter sprint.
The `.tail()` function returns the last n rows of a dataframe. So, `race.tail()` will display the last n rows of the `race` dataframe.
Given that `n` is not specified in the question, we need to determine the number of rows that will be displayed by `race.tail()`.
Looking at the options provided, the correct answer is:
"last three rows of the table"
So, the correct response is:
last three rows of the table
