Which of the following is NOT included in the Statistics Canada definition of "family"?

A) a widowed father living with his never-married daughter
B) a brother and sister sharing an apartment
C) a 12-year-old boy living with his mother
D) a common-law couple

According to Statistics Canada, a family is defined as "a married or common-law couple and the children, if any, of either and/or both spouses; a lone parent of any marital status with at least one child living in the same dwelling and that child or those children; a grandparent or other relative with no parents present, caring for children because the parents are unable to do so; or two or more persons who are related by blood, marriage, common-law or adoption, and who share a dwelling." Therefore, a brother and sister sharing an apartment would not be considered a family unit under this definition.
