Which two components must a clause contain?

A clause must contain both a subject and a verb to be considered a complete clause. The subject indicates what the clause is about (who or what is performing the action), while the verb describes the action or state of being. For example, in the sentence "She runs," "she" is the subject and "runs" is the verb, forming a complete clause.

The other choices do not meet the criteria for forming a clause. A noun and a preposition, or an adverb and an object do not ensure the necessary action or subject matter to create a complete thought. Additionally, a predicate refers to the part of the sentence that tells what happens to the subject, and while it does include the verb, it is not one of the essential requirements by itself. Hence, the correct identification of a clause hinges on the presence of both a subject and a verb.
