Answer:
Independent clause.
Explanation:
A independent clause contains at least one subject & one verb. They are stand alone and can be known as a simple sentence.
In this case, both a subject & verb is provided.
Subject: A subject of a sentence is typically described as <em>the person, place or thing</em>.
Verb: A verb of a sentence is typically described as <em>the action taken by the said subject</em>.
In this case:
The subject is the faucet (thing).
The Verb is dripped (past tense action of dripping).
Therefore, "The faucet dripped" is a independent clause.
