Final answer:
The subordinate clause among the given options is 'As soon as we made it home,' because it cannot stand alone as a complete sentence and it starts with the subordinating conjunction 'as soon as.'
Step-by-step explanation:
The question concerns identifying a subordinate clause among the given options. A subordinate clause, also known as a dependent clause, is a group of words that has a subject and a verb but cannot stand alone as a sentence. Instead, it must be connected to a main clause because it provides additional information but doesn't express a complete thought. Among the given options, "As soon as we made it home" is the subordinate clause. This clause cannot stand by itself to form a complete sentence and begins with the subordinating conjunction "as soon as".
