A. Slash
B. Hashtag
C. Comma
D. Exclamation mark
🧠 Explanation:
A hashtag is not a punctuation mark, unlike commas or periods, which structure sentences. Hashtags, used in social media, categorize content or trends, functioning as metadata tags. Punctuation marks clarify meaning in writing, while hashtags serve digital navigation, making them distinct. This difference is key in understanding language evolution in the digital age, where hashtags have become cultural tools for communication. Recognizing their role versus traditional punctuation aids in mastering modern writing and social media strategies, essential for digital literacy and online engagement.
