Answer:
b) Both an independent clause and a subordinate clause, when standing alone, are
followed by a period to end the sentence.
Explanation:
An independent clause is a group of words that has a subject and predicate but can make complete sense on their own.
EXAMPLE of an independent clause is "He opened the door"
EXAMPLE of a dependent clause is "when he heard the knock"
"He opened the door" can stand on its own and make perfect sense and can be ended with a period.
"when he heard the knock" is dependent and isn't usually ended with a period when standing alone.
Putting the clauses together, we have, "He opened the door when he heard the knock. " and this is a complex sentence.
