Answer
tail(), tail(5)
Reason — The syntax to display the last n rows of a Series object is <Series Object>.tail([n]). Therefore, according to this syntax, tail(5) will display last five rows of a Series object S. If n value is not specified, then tail() will return the last 5 rows of a Series object.
