A necklace is made by stringing N individual beads together in the repeating pattern red bead, green bead, white bead, blue bead and yellow bead. If the necklace begins with a red bead and ends with a white bead, then N could be:	Choose the correct choice from the following.
A) 16	B) 32	C) 54	D) 68	E) 86
R G W B Y is the bead pattern and it repeats.   Bead want to end with White.   So, the 3rd, 8th, 13th, 18th... beads will be W.   So, number of beads - 3 has to be divisible by 5 for it to be a White bead.   For those conditions, option D(68) only satisfy.   i.e., 68 - 3 = 65 and that also divisible by 5.   S0, 68   ANSWER:68
