– UserB must be able to select, update, delete, and insert data to the database tables.

Answer:
Box 1:
db_ddladmin: UserC
UserC needs to be able to add tables and procedures. He can do these through the db_ddladmin role (through the create statement).
Members of the db_ddladmin fixed database role can run any Data Definition Language (DDL) command in a database.
DDL is abbreviation of Data Definition Language. It is used to create and modify the structure of database objects in database.
Examples: CREATE, ALTER, DROP statements
Box 2:
db_datareader: UserB
UserB needs to be able to select data.
Members of the db_datareader fixed database role can run a SELECT statement against any table or view in the database.
Box 3:
db_datawriter: UserB
UserB needs to update, delete, and insert data. He can do these through the db_datawriter role. Members of the db_datawriter fixed database role can add, delete, or change data in all user tables.
Box 4:
db_owner: <leave blank>
Not required in this scenario.
Members of the db_owner fixed database role can perform all configuration and maintenance activities on the database.
Box 5:
db_acccessadmin: UserA
This enables UserA to provide Windows logins access. Members of the db_accessadmin fixed database role can add or remove access for Windows logins, Windows groups, and SQL Server logins.
