Final Answer:
B. Our national capital is named for Washington, and many American colleges and towns bear his name.
Step-by-step explanation:
The correct sentence is option B, "Our national capital is named for Washington, and many American colleges and towns bear his name." This option introduces a conjunction ("and") to properly connect the two related clauses. The original sentence lacked a coordinating conjunction, making it a run-on sentence. The revised version improves clarity and grammatical structure.
In formal writing, it's important to use appropriate punctuation and conjunctions to convey ideas effectively. Coordinating conjunctions like "and" help connect independent clauses and prevent sentence fragments. This correction aligns with proper grammar rules, ensuring the sentence is well-constructed and conveys the intended meaning accurately.
