  5 choices for the 1st finger, 4 for the 2nd, etc so my answer is C, 5P4.

  Agree with C. This is a permutation problem whereby there is no replacement of selected items. Once the first ring goes onto the first finger, there will be 4 rings left to choose from for the 2nd finger and so on. B would have been the answer to: In how many ways can one select four rings out of 5.

  The answer was (E): 4^5 which I don't get either. I came out the same result as you guys. Can someone explain?

  E is clearly wrong. It is assuming that the same ring can be used again for another finger once picked.

  It will be 4^5 if you assume one can put all rings on a finger ie more than one ring per finger is possible.

  I guess I built in an assumption that wasn't in the problem. I thought that you couldn't have more than 1 ring on each finger. I understand the answer now.
