Answer:
The correct answer or the exercise is:
C. An independent clause
Step-by-step explanation:
The reason this is the correct answer is that a) A dependant clause does not express a complete thought, so it is incomplete.
b) a dependent phrase is a type of construction that contains a subject and an object but not a complete thought.
d) an independent phrase can stand alone, however, it doesn't complete a thought.
Therefore c) is the correct option. Because it contains a subject, and object, connecting two different ideas that can complement each other.
