A Correct answer
Explanation

In a locally managed tablespace with UNIFORM SIZE specification, all extents are allocated at the uniform size specified (1 MB in this case). The extent is the basic unit of allocation - not segments, Oracle blocks, or OS blocks. Each extent will be exactly 1 MB regardless of the segment size or Oracle block size. This simplifies space management and reduces fragmentation.
