2. basketball
This is a classic case of overloading in C++. You have 2 functions, both named "printSport", but one of the functions receives an input of type double, and the other receives an input of type int. The specified method call passes a parameter of type int, so the version of printSport is called that receives a parameter of type int. And that version of printSport only prints the word "basketball". The other version of printSport is never called at all.
