The correct answer is A. Hannah Teter has won medals in several Olympic games: 2003 Aspen, 2006 Turin, and 2010 Vancouver
Explanation:
In grammar, the colon (:) is mostly used to introduce a list or set of elements that explain a previous sentence. This means the colon should be placed right before the elements it introduces and besides this, it can only be included if the previous sentence is independent. According to this, in the sentence "Hannah Teter has won medals in several Olympic games: 2003 Aspen, 2006 Turin, and 2010 Vancouver" the colon should be placed after the word "games" and before "2003 Aspen" because "2003 Aspen, 2006 Turin, and 2010 Vancouver" is the list of items that explain the Olympic games Hannah Teter participated in, also by placing the colon in this position the first sentence is complete and independent.
