  • A.348 28 326 158 279 236
  • B.348 28 326 236 158 279 
  • C.348 28 326 158 279 326
  • D.348 28 158 326 236 279 

Answer: A

Correct answer: 348 28 326 158 279 236

The order is 348, 28, 326, 158, 279, 236. The first three moves give 348 158 279 28 326 236, then 348 28 158 279 326 236, then 348 28 326 158 279 236. At that point 158, 279 and 236 are already in positions four, five and six, so nothing further moves and step 3 is the last.
