In the database schema shown in the images, there are four rows (excluding the header row) representing data entries for four people (John, Jane, Allison, and Anna).
Each row represents a record in the database table, also known as a tuple. The term record refers to a complete set of fields (ID, Name, and Age) for one entry. So, counting the four rows:
* John
* Jane
* Allison
* Anna
That makes a total of 4 records in the database schema.
Reference:The official CompTIA ITF+ Study Guide states:
" A record (or tuple) in a database is a complete set of fields that represents one entity - for example, a single row in a database table. " Thus, the correct answer is B.
