Answer:C

Since one can travel directly from City A to City B by bus, ship, or train, this problem can be considered in three cases.

Taking the bus gives 3 ways, taking the ship gives 2 ways, and taking the train gives 6 ways.

Therefore, the total number of ways to travel from City A to City B is 3 + 2 + 6 = 11 \quad \text{(ways)}.
