A compound sentence is a sentence that consists of two independent clauses joined by a coordinating conjunction. The compound sentence with a correct punctuation among the given sentences above is option B. Dr. Mitchell is my family physician, and his office is near my home. It is a general rule that the comma should come first before the coordinating conjunction.
Tone is elevated in the opening words - the organization of the words 'We hold these truths to be self-evident' sounds nobler than saying 'We believe this'. The parallelism of stating each right in a dependent clause beginning with that adds power and rhythm to the ideas.
