Explanation:

A colon is used to introduce an explanation or list. In the correct sentence, "the ruins of Bernard de Marigny de Mandeville’s sugar mill" explains "where they were going", and the colon is placed after a complete clause ("After half an hour, they finally got to where they were going"). Other options misplace the colon (e.g., before a clause, in the middle of a phrase).

Answer:

B. After half an hour, they finally got to where they were going: the ruins of Bernard de Marigny de Mandeville’s sugar mill.
