The Correct answer would be C, She can use a complex query linking students scores by name and available study period, then sort the data and group it.

Explanation:

Databases are used to store large number of data. Data are stored in the form of tables. These data can be identified by using the special keys for each table. Every table has a unique identification key, which is called the Primary key for that table and data can be retrieved by putting a query in the database. So in this example, Samantha wants to make groups of students according to their scores and time tables/schedules. So she has to use a complex query to link these two tables of student scores and student schedule to sort them in another table.
