Final answer:
The correct option is A) Period, comma, semicolon.The correct ways to separate independent clauses are with a period, a semicolon, or a comma accompanied by a coordinating conjunction.
Step-by-step explanation:
The three ways to separate complete sentences, or independent clauses, from one another are a period, a semicolon, and a comma with a coordinating conjunction. This can be denoted by using a period to mark the end of a declarative or imperative sentence. Independent clauses can also be connected using a semicolon; this method is especially useful when the sentences are closely related in content and the writer wishes to show a stronger connection than is provided by a period.
Lastly, independent clauses can be joined with a coordinating conjunction (for, and, nor, but, or, yet, so) preceded by a comma. Here's an example to illustrate: 'I finally found my keys, and I got to work just in time.' Additionally, a semicolon may be used with a transitional phrase, such as in 'It rained heavily during the afternoon; however, we still managed to have a picnic.' Therefore, the correct option is A) Period, comma, semicolon.
