This question is asking us to choose the two statements that would necessarily make the given piece of information true. The given information states that fifty candidates sat for the examination.

Statement I says that twenty candidates answered under half the questions. This means that less than 25 questions were answered by these twenty candidates.

Statement II says that there were ten failures in the examination. This means that ten candidates did not pass the examination.

Statement III says that over half the questions were answered by thirty candidates. This means that more than 25 questions were answered by these thirty candidates.

Statement IV says that forty candidates were successful. This means that forty candidates passed the examination.

We need to choose the two statements that would necessarily make the given piece of information true.

From the given statements, the two statements that would necessarily make the given piece of information true are Statement II and Statement IV. Therefore, the correct answer is Option B: II and IV.

Choosing Statement II and Statement IV ensures that there were ten failures and forty successful candidates, which adds up to the total of fifty candidates who sat for the examination.
