Show answer & explanation

Correct answer: B. Misunderstandings can arise from poor communication, but clear dialogue prevents many conflicts.

Option B correctly uses a comma before the coordinating conjunction 'but' to join two independent clauses. The other options either misuse the comma or incorrectly punctuate the conjunction.

Why the other options are wrong

  • A. This option incorrectly uses a comma before 'therefore'; 'therefore' is a conjunctive adverb and requires a semicolon before it if joining two independent clauses.
  • C. This option incorrectly places a comma before 'it' when 'and' joins two independent clauses; the comma should be before 'and'.
  • D. This option incorrectly uses a comma before 'however'; 'however' is a conjunctive adverb and requires a semicolon before it if joining two independent clauses.

Comma with Coordinating Conjunctions

A comma is used before a coordinating conjunction (for, and, nor, but, or, yet, so) when it connects two independent clauses.

  • Connects two complete thoughts (independent clauses).
  • The comma always precedes the conjunction.
  • FANBOYS is a common mnemonic for coordinating conjunctions.

Memory trick: FANBOYS connect, comma before they project.
