It is a rambling sentence.

Answer 1

It is a complete and correct sentence.

Answer 2

The sentence is a complete and correct sentence. Option A is correct.

A complete sentence is made up of three elements: a subject, verb, and an object. The subject is usually a noun or a pronoun. Besides, since there's a subject, there will be a verb due to the fact that all verbs need a subject. What is more, the object of a sentence is the element that acts upon by the subject. Moreover, sometimes commas play an importal role in a complete sentence.
