  1. ACARFTION
  2. BFRACNOIT
  3. CNOITCARF
  4. DCARFNOITCorrect

Explanation

The code works by dividing the word into two equal halves and reversing the letters within each half. For SYSTEM, the two halves are SYS and TEM. Reversing each gives SYS and MET, resulting in SYSMET. For NEARER, the two halves are NEA and RER. Reversing each gives AEN and RER, resulting in AENRER. For FRACTION, which has eight letters, the two halves are FRAC and TION. 1. Reverse FRAC to get CARF. 2. Reverse TION to get NOIT. Combining these gives CARFNOIT. Therefore, option D is correct.
