Any month of the year that starts with a Sunday will certainly have a Friday the 13th. There is at least one Friday the 13th in every calendar year. There can be as many as three Friday the 13ths within a single calendar year.

Such months will usually have 5 Sundays as well, with the exception of February in non-leap year, which will have only 4 Sundays. So, only one answer is correct.
