A data structure containing a series of records could be:Group of answer choicesa file.Both A and B.an array of records.a multi-dimensional array.

The correct answer is "Both A and B."

Here's why:

a) A file: A file can indeed be a data structure that contains a series of records. This is especially true in the context of databases, where data is often stored in file systems.

b) An array of records: An array is a type of data structure that can hold a fixed number of elements of a single type. In this case, if the type is a record, then an array can indeed hold a series of records.

c) A multi-dimensional array: While a multi-dimensional array can hold multiple data items, it's not specifically designed to hold a series of records. Therefore, this option is not correct.

So, the answer is "Both A and B" because both a file and an array of records can be a data structure that contains a series of records.
