Read each sentence to find out whether there is any grammatical error in it. The error, if any will be in one part of the sentence. The letter of that part is the answer. If there is no error, the answer is 'D'. (Ignore the errors of punctuation, if any). (solve as per the direction given)

The sentence reads: "Many times the news has been published in the papers that the end of the world will be certain if a nuclear war breaks out." Let's break it down to identify any grammatical error:

1. Option A - Many times the news has been published:
   • This part is grammatically correct. The phrase "many times" is acceptable when referring to something that happens repeatedly in the past, and the verb tense "has been published" is also correct in this context.
2. Option B - in the papers that the end of the world will be certain:
   • The phrase "the end of the world will be certain" is awkwardly phrased. The word "certain" here doesn't work well with the structure of the sentence. A better construction would be "the end of the world is certain" or "it is certain that the end of the world will come," making the sentence more logical and fluent.
3. Option C - if a nuclear war breaks out:
   • This part is grammatically correct. The conditional clause "if a nuclear war breaks out" is properly structured.
4. Option D - No error:
   • There is an error in Option B with the phrasing of "the end of the world will be certain." Therefore, Option D is not correct.
5. Final Answer:
   • The error is in Option B. The correct answer is B.
