To answer this question, you need to understand the file extensions used for shared object repository (SOR) files and local object repository (LOR) files.
Option A) (.TSR and .QRS) - This option is incorrect because the file extension .TSR is not used for shared object repository files, and the file extension .QRS is not used for local object repository files.
Option B) (.QRS and .MTR) - This option is incorrect because the file extension .QRS is not used for shared object repository files. The file extension .MTR is used for the recovery scenario file, not for local object repository files.
Option C) (.TSR and .MTR) - This option is correct. The file extension .TSR is used for shared object repository files, and the file extension .MTR is used for local object repository files.
Option D) (.MTR and .QFL) - This option is incorrect because the file extension .MTR is not used for shared object repository files, and the file extension .QFL is not used for local object repository files.
The correct answer is Option C. The file extension of the shared object repository file is .TSR, and the file extension of the local object repository file is .MTR.
