When typing a dash, how should the hyphens be spaced?

When typing a dash, particularly an en dash or em dash, the convention typically requires specific spacing. For the choice indicating that one space should be placed before and after the hyphen, this aligns with standard punctuation practices, especially in formal documents and writing styles. Using spaces around the dash helps to visually distinguish it from surrounding text and enhances readability.

This formatting is especially relevant in contexts where clarity is paramount, such as in academic or professional writing. The use of spaces allows both the dash and the text to flow better visually, ensuring that the reader can easily follow the sentiments or concepts being expressed.

In contrast, the other options present either incorrect formatting or a misunderstanding of the dash's function, which is why they do not serve as the correct answer. Hence, the need for proper spacing around the dash aligns with accepted standards in keyboarding and written communication.
