Source: — Sentence Correction |

In this statement, the author is trying to explain that ulcers are caused not by stress... But by a bacterium

Option A - Incorrect
This option is incorrect because there is no relation between the sentence and what the author wants to say.

Option B - Incorrect
In this sentence, 'not caused by' is not parallel to 'are by'. It doesn't explain what the author wants to say.

Option C - Correct
The sentence is parallel to the given... The use of 'not by' ... 'but by' makes it parallel.

Option D - Incorrect
There's no parallelism between 'by stress' and 'a bacterium'. The first sentence is a prepositional phrase while the second is a noun.

Option E - Incorrect
The sentence is not parallel because 'by stress' is not parallel to 'are by a bacterium' because the first sentence is a prepositional phrase while the second one starts with a verb.
