What describes the 'allocateDirect()' method's allocated buffers?

Always larger than requested
Possibly more efficient for I/O
Only usable with 'FileChannel'
Not usable with compression classes

The correct answer is: Possibly more efficient for I/O

The 'allocateDirect()' method's allocated buffers may potentially be more efficient for I/O compared to using 'allocate()', as it avoids an extra copy step. This means that while the other options may apply to certain situations, they are not generally true for 'allocateDirect()' buffers. Option A, for example, might be correct in some cases, but not always. Similarly, options C and D are only applicable in specific situations and do not apply to the method as a whole.
