E. a contingency table
Step-by-step explanation:

The survey was conducted to study the relationship between:
1) Whether the family is buying or renting their homes
This is a categorical variable with 2 possible options
2) Marital Status of the Parents
This is also a categorical variable with 4 possible options: Married, single, divorced, and widowed
This means, we have to display 2 categorical variables side by side, showing their relationship. To display such data we always use a contingency table.
A contingency table or a 2-way table is a type of Frequency Distribution that is used to summarize the relationship between two or more Categorical Variables. Its similar to matrix form i.e. in form of rows and columns of a table. The minimum size is 2 rows and 2 columns.
An example of the contingency table that can be drawn for a data collected in a similar survey is shown in the image below.
