Answer:
The correct answer is letter A
Step-by-step explanation:
Option A: the first colon before the list of cities is being used correctly as there is a complete independant clause before it. Also, there is a list of elements after the second colon; the semicolon is before the conjunction 'and' separating the last element from the two before ( it is not comma but semicolon because they are cities that belong to bigger places that are the states). Finally, the preposition 'in' is not before the colon.
