The correct answer is, Their family can be described as a Beanpole Family.

Explanation:

A beanpole family is a family which has a long but thin family structure. There are lesser number of children in each of the family in the structure. Ties between such families are considered the strongest. Inter-generational ties are firm even they don't meet or catch up often or live oceans cross. So in this question, Laurie's mother and father were single children of their families, also Laurie has one brother, and further they both have only one child each. So the structure of the family is thin and thus described as the Beanpole Family.
