Question

Which of the following is the correct way to rewrite the following run-on sentence?

Answer 1

Answer:

B. Mike joined the Army, and he became more disciplined during the training.

Explanation:

Option B is the correct way to rewrite the run-on sentence because the two main independent clauses "Mike joined the Army" and "he became more disciplined during training" are joined by a connecting word "and" and a punctuation mark(comma). Both clauses are related thoughts.  In other options the clauses are not joined correctly.
