Find the correct order of unit process in tablet compression:

Assertion A: The small engraved area in letter like "A", "B" and "O" are difficult to tablet manufacture cleanly. Reason R: Because tablet punches having engraving exhibit picking problem in compression.

Assertion A: Compression distillation is conducted at high pressure and temperature. Reason R: It produces pyrogen free water hence popular in pharmaceutical industries.
