Final answer:
The group of words "That I like your tie" is a clause because it contains both a subject ('I') and a verb ('like'). It is a dependent clause as it cannot stand alone as a complete sentence. The correct option is (a) Clause.
Step-by-step explanation:
The group of words "That I like your tie" forms a clause because it contains both a subject and a verb. The subject is "I" and the verb is "like".
However, this clause is a dependent clause because it does not express a complete thought and relies on an independent clause to form a complete sentence. For example, in the sentence "I didn't say that I like your tie," the group of words "that I like your tie" is a dependent clause that adds extra information to the independent clause "I didn't say."
In contrast, a phrase is a group of words that acts as a single part of speech within a sentence but lacks a subject-verb component. Examples of phrases include noun phrases, verb phrases, and prepositional phrases. These groups of words work together to perform a specific function but cannot stand alone as a complete thought.
Therefore, the correct option is (a) Clause.
