"At least 2" simply means 2 or more.
2 cities can be selected from 4 cities in 4C2 ways and these two cities, let's say A and B would have two distinct itineraries AB and BA.
Mathematically, that can be done either in 4C2*2! or 4P2 ways = 12.
Also, 3 cities in 4C3*3! or 4P3 ways = 24; that is, 4 cities in 4C4*4! or 4P4 ways = 24.
Total 12+24+24=60 ways.
The correct option is C

Given that Noah has a coin collection. He keeps 7 collecting coins in his box, which is 20% of the coins he has. The total number of the coins will be calculated as:-
Number of the coins = 7 / 0.2
Number of the coins = 35
Therefore, the total number of coins will be equal to 35.
