Answer: Option C

Solution(By Examveda Team)

When using the SQL INSERT statement, rows can either be inserted into a table one at a time or in groups. This means that you can insert multiple rows into a table with a single INSERT statement, making it more efficient for mass data insertion. Option C is the correct choice, while Options A, B, and D do not accurately describe the capabilities of the INSERT statement.
