I think that none of the possible answer choices is correct.
We can see the problem as a combination with repetition problem.
We have to choose five among six elements. The order does not matter and we can repeat elements.
The solution would be C(6+5-1,5) = C(10,5)

I found 28 different choices of trip
A---1---2---3---4---5---6---B
from A -> 7 possibilities (A1, A2, A3, ..., AB)
from 1 -> 6 possibilities
.....
from 6 -> 1 possibilities
total : 7+6+5+4+3+2+1 = 28
28C5 but it is not a potential answer, am i missing something ?
