Explanation
Four Kings accepted Islam when the holy prophet sent them letters. This answer is correct because historical records show that the Prophet Muhammad sent letters to several kings and rulers of his time, and four of them are known to have accepted Islam after receiving these letters, due to the persuasive and spiritual nature of the messages. The QuizMaster of AnsweringExams.Com suggests remembering this fact by associating it with the year 628 CE, when these events are believed to have occurred, and the number 4 can be linked to the four directions or the four seasons to make it more memorable. The other options are incorrect because they do not align with the documented historical accounts of the Prophet’s interactions with these kings.
