The phrase "which of the following is" is commonly used in English to introduce a multiple choice question where the respondent is asked to select one correct option from a given list. The phrase means "choose one from the list that follows." It is grammatically correct to use "which of the following is" when expecting a single correct answer, whereas "which of the following are" is used when multiple correct answers are possible. The phrase "which of the followings" is incorrect because "following" is an adjective and cannot be pluralized. Also, "which of the below" is grammatically incorrect unless it is followed by a plural noun. Common synonyms for the phrase include "which of these," "which one," and "which answer".
If the question intended was about options to "which of the following is correct," it depends on the context or options provided, usually focusing on a factually or logically correct statement from a list.
Please specify the options or context related to "which of the following is" for a precise selection or evaluation.
