Answer:
A. I am a good communicator, and I am a strong team member.
Step-by-step explanation:
The phrase "I am a good communicator, and I am a strong team member" has the correct use of the comma. This makes the sentence coherent and cohesive so that the reader correctly understands its meaning.
A comma is a grammatical mark that indicates a syntactic shift. A sentence that is not in direct order (with subject, verb and complements) needs a mark in writing, with some graphic sign, indicating that this change of order has been made.
Knowing how to apply the comma requires understanding of several other grammatical topics - such as the direct order of the terms of the sentence, what is a subject, what is an object, the place of the verb, what is an adverbial adjunct and its place in prayer , etc. There are many questions that need to be clear to the student so that he can apply the comma well.
