Final answer:
The answer is option C. The data type returned by a BMQL statement is a RecordSet.
Step-by-step explanation:
The data type that is returned by a BMQL statement is a RecordSet. A RecordSet is a collection of data that contains multiple fields and records. Each field represents a specific piece of information and each record represents a set of related information.
For example, if a BMQL statement is used to query a database table containing student information, the RecordSet that is returned may contain fields like 'Name', 'Age', and 'Grade', with each record representing a specific student's information.
Therefore, option C, RecordSet, is the correct answer to the question.
