Which of the following sentences uses correct punctuation? a. i am a good communicator, and i am a strong team member. b. i communicate well, i am a strong team member. c. i am a good fit for the job, i have the right experience. d. i have excellent telephone skills, i am detail oriented.

Option (A) I am a good communicator, and I am a strong team member.

Explanation:

In option (A), there is a correct usage of comma before the coordinating conjunction (and)—a word that joins two independent clauses.

First independent clause: I am a good communicator.

Second independent clause: I am a strong team member.

Coordinating conjunction: and

Whenever we connect two independent clauses by using the coordinating conjunction, there must be a comma before a coordinating conjunction.

In rest of the options, two independent clauses are incorrectly connected with each other by using just a comma and no coordinating conjunction.

Bonus: You can also connect two independent clauses without using a coordinating conjunction. In that case, use semi-colon instead of comma between two independent clauses. "I communicate well; I am a strong team member," is one example.
