Which punctuation mark is often used to indicate a range?

The en dash is the correct choice because it is specifically used in writing to indicate a range between two numbers, dates, or values, such as "pages 10–20" or "January 1, 2023 – December 31, 2023." This usage conveys a span or distance between the two endpoints.

The en dash is distinct from a hyphen, which primarily connects words (like in compound terms) rather than indicating a range, while a semicolon typically links independent clauses without establishing a numerical or chronological range. Colons are used to introduce a list, a quote, or an explanation rather than denote a range. Each of these other punctuation marks serves different purposes in writing, making the en dash the appropriate choice for indicating range.
