Explanation

Safar is the second month of the Islamic calendar, making option B correct. However, based on common knowledge and standard Islamic calendar order, Muharram is the first month, and Safar is the second month, so the current answer B is actually correct according to general knowledge. Re-evaluating: The question asks for which month Safar *is*. Safar is definitively the second month. Therefore, the current answer B is correct.
