Dataverse identifies the two types of relationships between tables: One-to-Many (1:N) and Many-to-Many (N:N). 
A One-to-Many relationship is a Parent-Child relationship, like between a company and its employees. 
A Many-to-Many relationship is when multiple records from one table have the relationship with the multiple records in another table and vice versa. When users create a Many-to-Many relationship, Dataverse creates a specific intersect matching table between the records in two tables. After you create an N:N relationship, you cannot edit records in both tables. Connections are a special case for the Many-to-Many relationships. They are flexible and don`t have the limitations of the N:N relationship. 
The Survey table has a relationship with three tables: RentCenters, Customers, CarFleet. Every record in a Survey table has the lookup field for the rent center code or name, the customer id, and information about the car: car id, type, make, and model. The Survey table has a Many-to-One relationship between all three tables. When we want to extend information from the parent table, we can create a mapping between tables. As a result, the mapped field will be copied to the related table, like car type, make, and model from the CarFleet table. Options B is correct because we need to create a One-to-Many relationship between Customers and the Survey table or Many-to-One from the Survey table.
Options D and G are correct because we need to create One-to-Many relationships between CarFleet and Survey tables and between RentCenters and Survey tables.
Option H is correct because we need to map the fields from the CarFleet table into the Survey table.
You can view the mappable columns in the classic interface (Number 1) for the entity (Number 2) and 1:N Relationships (Number 3). The Type (Number 4) drop-down helps to filter the mappable table and columns (Number 5). 

All other options are incorrect.
