Correct Answer: Fathers, Uncles, Brothers

Solution : Let's check the options –
First option: Police Officers, Doctors, Nurses; These are the professions and do not have a common relation to them. Therefore, this is incorrect.
Second option: Artists, Fathers, Girls; some girls and fathers may be artists but there is no common region between fathers and girls. Therefore, this is not the correct relation.
Third option: Brothers, Males, Females; All brothers come under the category of males so, the circle of brothers completely lies under the circle of males but males and females do not have any common region. Therefore, this is incorrect.
Fourth option: Fathers, Uncles, Brothers; Some fathers may be uncles and brothers, and some uncles may be fathers and brothers. Similarly, some brothers are fathers and uncles. Therefore, all the terms have a common region between them.
