The correct answer is C. The German air force defeated the polish air forced and bombed major Plush cities, and world war 2 began in 1939.
Step-by-step explanation:
In grammar, coordination refers to the use of words such as and, or, so, but, yet to link two ideas of the same importance and topic. Additionally, faulty coordination occurs if the sentences are not correctly linked or do not have a logical relationship. This type of error occurs in "The German air force defeated the polish air forced and bombed major Plush cities, and world war 2 began in 1939" because the use of "and" before "world war 2 began in 1939" suggests the two events are closely connected; however, these are not logically related as Germany victory over Polland did not lead to the beginning of the second world war and therefore the coordination is illogical or faulty.
