Why each option

To quickly integrate structured data into an Oracle database, direct-path `INSERT` SQL statements offer the fastest method by bypassing the buffer cache and writing data directly to data files.

Ausing the DBVERIFY utility

The `DBVERIFY` utility is used for checking the integrity of Oracle data files and is not a mechanism for data distribution or loading.

Busing direct-path INSERT SQL statementsCorrect

Direct-path `INSERT` statements, typically using the `/*+ APPEND */` hint or the `APPEND` clause, achieve high performance by bypassing the SQL buffer cache and writing new data directly to the end of segment data files. This method minimizes I/O and CPU overhead, making it significantly faster for bulk data integration compared to conventional inserts.

Cusing SQL*Loader

`SQL*Loader` is a utility for bulk loading data from external files into Oracle tables, and while it can use direct path mode, the question specifically refers to `direct-path INSERT` SQL statements.

Dusing RMAN transportable tablespace operation

An RMAN transportable tablespace operation is used to move an entire tablespace between Oracle databases and is not a platform-agnostic method for general data distribution.
