Explanation:

Dashes are punctuation marks used mainly to separate two or more words from the main sentence elements, these dashes are also called long dashes or em dashes because they are longer than the en dash (-) and serve to introduce additional information that clarifies or explains one section of the sentence by acting as parentheses or commas, this also implies the set of words that are between the dashes are extra information but in terms of grammar do not belong to the main sentence and because of this they should be separated. Considering this, the sentence that correctly places the dashes is "People of average height—less than six feet tall—have had basketball careers" because in this sentence the information that clarifies the concept of "average height" which is extra information is placed between the dashes, which is one of the main functions of this type of punctuation mark.
