Which punctuation is used between sentences that are grammatically independent?

The correct answer is Semicolon.

• Why 'Semicolon' is correct: A semicolon (;) is used to connect two independent clauses that are closely related in meaning but could stand alone as separate sentences. It indicates a stronger pause than a comma but a weaker pause than a period, suggesting a close relationship between the ideas without using a coordinating conjunction.

• Why other options are incorrect:

  • 'Hyphen' (-) is used to join words or parts of words (e.g., well-known, sister-in-law), not to connect independent sentences.
  • 'Comma' (,) is used for various purposes like separating items in a list, introducing clauses, or joining independent clauses with a coordinating conjunction (e.g., and, but, or), but it cannot join two independent clauses on its own without creating a comma splice.
  • 'Colon' (:) is used to introduce a list, an explanation, or a quotation, or to emphasize a point, but not to simply connect two grammatically independent sentences in the way a semicolon does.
